53a291a435 Do not break git-gui messages into multiple lines.
Many git-gui messages were broken into a multiple lines to make
good paragraph width. Unfortunately in reality it breaks the paragraph
width completely, because the dialog window width does not coincide
with the paragraph width created by the current font.

Tcl/Tk's standard dialog boxes are breaking the long lines
automatically, so it is better to make long lines and let the
interpreter do the job.

df0cd69558 Improve look-and-feel of the git-gui tool.
Made the default buttons on the dialog active and focused upon the
dialog appearence.

Bound 'Escape' and 'Return' keys to the dialog dismissal where it
was appropriate: mainly for dialogs with only one button and no
editable fields, but on console output dialogs as well.

756d846fea git-gui: Allow 'git gui version' outside of a repository
I got a little surprise one day when I tried to run 'git gui version'
outside of a Git repository to determine what version of git-gui was
installed on that system.  Turns out we were doing the repository
check long before we got around to command line argument handling.

We now look to see if the only argument we have been given is
'version' or '--version', and if so, print out the version and
exit immediately; long before we consider looking at the Git
version or working directory.  This way users can still get to
the git-gui version number even if Git's version cannot be read.

c7bafad10d git-gui: Allow committing empty merges
Johannes Sixt noticed that git-gui would not let the user commit
a merge created by `git merge -s ours` as the ours strategy does
not alter the tree (that is HEAD^1^{tree} = HEAD^{tree} after the
merge).  The same issue arises from amending such a merge commit.

We now permit an empty commit (no changed files) if we are doing
a merge commit.  Core Git does this with its command line based
git-commit tool, so it makes sense for the GUI to do the same.

51bd9d7b8c git-gui: Don't create empty (same tree as parent) commits.
Mark Levedahl noticed that git-gui will let you create an empty
normal (non-merge) commit if the file state in the index is out
of whack.  The case Mark was looking at was with the new autoCRLF
feature in git enabled and is actually somewhat difficult to create.

I found a different way to create an empty commit:  turn on the
Trust File Modifications flag, touch a file, rescan, then move
the file into the "Changes To Be Committed" list without looking
at the file's diff.  This makes git-gui think there are files
staged for commit, yet the update-index call did nothing other
than refresh the stat information for the affected file.  In
this case git-gui allowed the user to make a commit that did
not actually change anything in the repository.

Creating empty commits is usually a pointless operation; rarely
does it record useful information.  More often than not an empty
commit is actually an indication that the user did not properly
update their index prior to commit.  We should help the user out
by detecting this possible mistake and guiding them through it,
rather than blindly recording it.

After we get the new tree name back from write-tree we compare
it to the parent commit's tree; if they are the same string and
this is a normal (non-merge, non-amend) commit then something
fishy is going on.  The user is making an empty commit, but they
most likely don't want to do that.  We now pop an informational
dialog and start a rescan, aborting the commit.

fd234dfdb7 git-gui: Add Reset to the Branch menu.
cehteh on #git noticed that there was no way to perform a reset --hard
from within git-gui.  When I pointed out this was Merge->Abort Merge
cehteh said this is not very understandable, and that most users would
never guess to try that option unless they were actually in a merge.

So Branch->Reset is now also a way to cause a reset --hard from within
the UI.  Right now the confirmation dialog is the same as the one used
in Merge->Abort Merge.

92446aba47 Don't modify CREDITS-FILE if it hasn't changed.
We should always avoid rewriting a built file during `make install`
if nothing has changed since `make all`.  This is to help support
the typical installation process of compiling a package as yourself,
then installing it as root.

Forcing CREDITS-FILE to be always be rebuilt in the Makefile means
that CREDITS-GEN needs to check for a change and only update
CREDITS-FILE if the file content actually differs.  After all,
content is king in Git.

This is instead of \, as \ gets escaped by the browser into its hex

372ef954a1 git-gui: Correct crash when saving options in blame mode.
Martin Waitz noticed that git-gui crashed while saving the user's
options out if the application was started in blame mode.  This
was caused by the do_save_config procedure invoking reshow_diff
incase the number of context lines was modified by the user.
Because we bypassed main window UI setup to enter blame mode we
did not set many of the globals which were accessed by reshow_diff,
and reading unset variables is an error in Tcl.

Aside from moving the globals to be set earlier, I also modified
reshow_diff to not invoke clear_diff if there is no path currently
in the diff viewer.  This way reshow_diff does not crash when in
blame mode due to the $ui_diff command not being defined.

26370f73c0 git-gui: Prefer version file over git-describe.
Some distributions are using Git for part of their package
management system, but unpack Git's own source code for
delivery from the .tar.gz.  This means that when we walk
up the directory tree with git-describe to locate a Git
repository, the repository we find is for the distribution
and *not* for git-gui.  Consequently any tag we might find
there is bogus and does not apply to us.

In this case the version file should always exist and be
readable, as the packager is working from the released
.tar.gz sources.  So we should always favor the version
file over anything git-describe guess for us.

I started to find it confusing that git-gui would refer to itself
as git-citool when it was started through the citool hardlink, or
with the citool subcommand.  What was especially confusing was the
options dialog and the about dialog, as both seemed to imply they
were somehow different from the git-gui versions.  In actuality
there is no difference at all.

Now we just call our options menu item 'Options...' (skipping the
application name) and our About dialog now always shows git-gui
within the short description (above the copyleft notice) and in
the version field.

cdf6e08880 git-gui: Permit merging tags into the current branch.
It was pointed out on the git mailing list by Martin Koegler that
we did not show tags as possible things to merge into the current
branch.  They actually are, and core Git's Grand Unified Merge
Driver will accept them just like any other commit.

So our merge dialog now requests all refs/heads, refs/remotes and
refs/tags named refs and attempts to match them against the commits
not in HEAD.  One complicating factor here is that we must use the
%(*objectname) field when talking about an annotated tag, as they
will not appear in the output of rev-list.

54acdd95b8 git-gui: Basic version check to ensure git 1.5.0 or later is used.
This is a very crude (but hopefully effective) check against the
`git` executable found in our PATH.  Some of the subcommands and
options that git-gui requires to be present to operate were created
during the 1.5.0 development cycle, so 1.5 is the minimum version
of git that we can expect to support.

There actually are early releases of 1.5 (e.g. 1.5.0-rc0) that
don't have everything we expect (like `blame --incremental`) but
these are purely academic at this point.  1.5.0 final was tagged
and released just a few hours ago.  The release candidates will
(hopefully) fade into the dark quickly.

they want while the tool is running, we jump to the first line
of the first annotation if the user has not already clicked on

at the very top of the file.

Since it takes a second (at least on my PowerBook) to even generate
the first annotation for git-gui.sh, the user should have plenty of
time to adjust the scrollbar or click on a line even before we get
that first annotation record in, which allows the user to bypass
our automatic jumping.

6910ae80d0 git-gui: Redesign the display of annotated files.
Using 180 columns worth of screen space to display just 20 columns of
file data and 160 columns worth of annotation information is not
practically useful.  Users need/want to see the file data, and have
the anotation associated with it displayed in a detail pane only when
they have focused on a particular region of the file.

Now our file viewer has a small 10-line high pane below the file
which shows the commit message for the commit this line was blamed
on.  The columns have all been removed, except the current line
number column as that has some real value when trying to locate an
interesting block.

To keep the user entertained we have a progress meter in the status
bar of the viewer which lets them know how many lines have been
annotated, and how much has been completed.  We use a grey background
on the line numbers for lines which we have obtained annotation from,
and we color all lines in the current commit with a yellow background,
so they stand out when scanning through the file.  All other lines
are kept with a white background, making the yellow really pop.

We now can start the single commit UI mode via `git-citool` and also
through `git gui citool`.

2ebba528dc git-gui: View blame from the command line.
Viewing annotated files is one of those tasks that is relatively
difficult to do in a simple vt100 terminal emulator.  The user
really wants to be able to browse through a lot of information,
and to interact with it by navigating through revisions.

Now users can start our file viewer with annotations by running
'git gui blame commit path', thereby seeing the contents of the
given file at the given commit.  Right now I am being lazy by
not allowing the user to omit the commit name (and have us thus
assume HEAD).

db7f34d4c5 git-gui: Optionally save commit buffer on exit.
If the commit area does not exist, don't save the commit message to
a file, or the window geometry.  The reason I'm doing this is I want
to make the main window entirely optional, such as if the user has
asked us to show a blame from the command line.  In such cases the
commit area won't exist and trying to get its text would cause an
error.

If we are running without the commit message area, we cannot save
our window geometry either, as the root window '.' won't be a normal
commit window.

64a906f861 git-gui: Separate transport/branch menus from multicommit.
These are now controlled by the transport and branch options, rather
than the multicommit option.

cf25ddc8b3 git-gui: Refactor single_commit to a proc.
This is a minor code cleanup to make working with what used to be the
$single_commit flag easier.  Its also to better handle various UI
configurations, depending on command line parameters given by the
user, or perhaps user preferences.
