e1622bfcba Protect scripted Porcelains from GREP_OPTIONS insanity
If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect.  For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.

The approach taken by this change to address this issue is to protect only
our own use of grep/egrep.  Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.

On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

0c3d3ac352 rebase: use plumbing to show dirty state
Commit 4cfbe06 introduced the use of "git diff" to show
dirty state in a format more familiar to users. However, it
should have used the plumbing "git diff-files" instead.

Not only is it good practice in general to use plumbing in
scripts, but in this case we really don't want the automatic
pager to kick in for an error message.

Previous version expose the output of the plumbing update-index to the

We still need to run update-index to refresh the cache (if

0e987a12fc am, rebase: teach quiet option
git-am and git-rebase are talkative scripts. Teach them to be quiet when
told, allowing them to speak only when they fail or experience errors.

The quiet option is maintained when git-am or git-rebase fails to apply
a patch. This means subsequent --resolved, --continue, --skip, --abort
invocations will be quiet if the original invocation was quiet.

Drop a handful of >&2 redirection; the rest of the program sends all the
info messages to stdout, not to stderr.

190f53232d rebase: learn to rebase root commit
Teach git-rebase a new option --root, which instructs it to rebase the
entire history leading up to <branch>.  This option must be used with
--onto <newbase>, and causes commits that already exist in <newbase>
to be skipped.  (Normal operation skips commits that already exist in
<upstream> instead.)

One possible use-case is with git-svn: suppose you start hacking
(perhaps offline) on a new project, but later notice you want to
commit this work to SVN.  You will have to rebase the entire history,
including the root commit, on a (possibly empty) commit coming from
git-svn, to establish a history connection.  This previously had to
be done by cherry-picking the root commit manually.

07e62b733f rebase: improve error messages about dirty state
If you have unstaged changes in your working tree and try to
rebase, you will get the cryptic "foo: needs update"
message, but nothing else.  If you have staged changes, you
get "your index is not up-to-date".

Let's improve this situation in two ways:

 - for unstaged changes, let's also tell them we are
   canceling the rebase, and why (in addition to the "needs
   update" lines)

 - for the staged changes case, let's use language that is a
   little more clear to the user: their index contains
   uncommitted changes

f8cca019b9 rebase: Support preserving merges in non-interactive mode
As a result of implementation details, 'git rebase' could
previously only preserve merges in interactive mode. That
limitation was hard for users to understand and awkward to
explain.

This patch works around it by running the interactive rebase
helper git-rebase--interactive with GIT_EDITOR set to ':'
when the user passes "-p" but not "-i" to the rebase command.
The effect is that the interactive rebase helper is used but
the user never sees an editor.

The test-case included in this patch was originally written
by Stephen Habermann <stephen@exigencecorp.com>, but has
been extensively modified since its creation.

"git rebase" without arguments on initial startup showed:

This patch makes it show the ordinary usage string.

If .git/rebase-merge or .git/rebase-apply/rebasing exists, git-rebase
will die with a message saying that a rebase is in progress and the user
should try --skip/--abort/--continue.

If .git/rebase-apply/applying exists, git-rebase will die with a message
saying that git-am is in progress, regardless how many arguments are
given.

If no arguments are given and .git/rebase-apply/ exists, but neither a
rebasing nor applying file is in that directory, git-rebase dies with a
message saying that rebase-apply exists and no arguments were given.

did not have -q option, but there is no reason to keep doing it anymore.

22e407951e Teach "am" and "rebase" to mark the original position with ORIG_HEAD
"merge" and "reset" leave the original point in history in ORIG_HEAD,
which makes it easy to go back to where you were before you inflict a
major damage to your history and realize that you do not like the result
at all.  These days with reflog, we technically do not need to use
ORIG_HEAD, but it is a handy way nevertheless.

This teaches "am" and "rebase" (all forms --- the vanilla one that uses
"am" as its backend, "-m" variant that cherry-picks, and "--interactive")
to do the same.

The original idea and a partial implementation to do this only for "rebase
-m" was by Brian Gernhardt; this extends on his idea.

0cb06644a5 rebase [--onto O] A B: omit needless checkout
This teaches "git rebase [--onto O] A B" to omit an unnecessary checkout
of branch B before it goes on.

"git-rebase" originally was about rebasing the current branch to somewhere
else, and when the extra parameter to name which branch to rebase was
added, it defined the semantics to the safest but stupid "first switch to
the named branch and then operate exactly the same way as if we were
already on that branch".

But the first thing the real part of "rebase" does is to reset the work
tree and the index to the "onto" commit.  Which means the "rebase that
branch" form switched the work tree to the tip of the branch only to
immediately switch again to another commit.  This was wasteful.
