382da4023f format-patch: fix parsing of "--" on the command line
When given a pathspec that does not match any path in the current work
tree with an explicit "--":

    git format-patch <commit> -- <path>

the command still complains that <path> does not exist in the current work
tree and the user needs to explicitly specify "--" and errors out.  This
is because it incorrectly removes "--" from the command line arguments
that is later passed to setup_revisions().

1d46f2ea14 format-patch: make "-p" suppress diffstat
Once upon a time, format-patch would use its default stat
plus patch format only when no diff format was given on the
command line. This meant that "format-patch -p" would
suppress the stat and show just the patch.

Commit 68daa64 changed this to keep the stat format when we
had an "implicit" patch format, like "-U5". As a side
effect, this meant that an explicit patch format was now
ignored (because cmd_format_patch didn't know the reason
that the format was set way down in diff_opt_parse).

This patch unbreaks what 68daa64 did (while still preserving
what 68daa64 was trying to do), reinstating "-p" to suppress
the default behavior. We do this by parsing "-p" ourselves
in format-patch, and noting whether it was used explicitly.

33e7018c45 git-log: allow --decorate[=short|full]
Commit de435ac0 changed the behavior of --decorate from printing the
full ref (e.g., "refs/heads/master") to a shorter, more human-readable
version (e.g., just "master"). While this is nice for human readers,
external tools using the output from "git log" may prefer the full
version.

This patch introduces an extension to --decorate to allow the caller to
specify either the short or the full versions.

ae03ee644e show: add space between multiple items
When showing an annotated tag, "git show" will always
display the pointed-to object. However, it didn't separate
the two with whitespace, making it more difficult to notice
where the new object started. For example:

  $ git tag -m 'my message' foo
  $ git show foo
  tag foo

  Author: Jeff King <peff@peff.net>

  ...

This patch respects and sets the rev.shown_one member to
prepend a blank line before showing a second item. We use
this member of rev_info instead of a local flag, because the
log_tree_commit we call into for showing commits already
respects and sets that flag. Meaning that everything will be
spaced properly if you intermix commits and tags, like:

  $ git show v1.6.3 v1.6.2 HEAD

In that case, a single blank line will separate the first
tag, the commit it points to, the second tag, the commit
that one points to, and the final commit.

While we're at it, let's also support trees, so that even
something as crazy as

  $ git show HEAD^{tree} HEAD~1^{tree} HEAD

will also be spaced in an easy-to-read way. However, we
intentionally do _not_ insert blank lines for blobs, so
that specifying multiple blobs gives a strict concatenation.

ca4ca9ed06 show: suppress extra newline when showing annotated tag
When showing a tag, our header parsing finishes with the
offset pointing to the newline separating the tag header
from the tag body. This means that the printed body will
always start with a newline.

However, we also add an extra newline when printing the
tagger information. This leads to an ugly double-newline:

    $ git show v1.6.3
    tag v1.6.3
    Tagger: Junio C Hamano <gitster@pobox.com>
    Date:   Wed May 6 18:16:47 2009 -0700

    GIT 1.6.3
    -----BEGIN PGP SIGNATURE-----
    ...

This patch removes the extra newline from the end of the
tagger headers. This is a better solution than suppressing
the separator newline, because it retains the behavior for
tags which have no tagger. E.g., "git show v0.99" will
continue to look like:

      $ git show v0.99
      tag v0.99

      Test-release for wider distribution.

2af202be3d Fix various sparse warnings in the git source code
There are a few remaining ones, but this fixes the trivial ones. It boils
down to two main issues that sparse complains about:

 - warning: Using plain integer as NULL pointer

   Sparse doesn't like you using '0' instead of 'NULL'. For various good
   reasons, not the least of which is just the visual confusion. A NULL
   pointer is not an integer, and that whole "0 works as NULL" is a
   historical accident and not very pretty.

   A few of these remain: zlib is a total mess, and Z_NULL is just a 0.
   I didn't touch those.

 - warning: symbol 'xyz' was not declared. Should it be static?

   Sparse wants to see declarations for any functions you export. A lack
   of a declaration tends to mean that you should either add one, or you
   should mark the function 'static' to show that it's in file scope.

   A few of these remain: I only did the ones that should obviously just
   be made static.

That 'wt_status_submodule_summary' one is debatable. It has a few related
flags (like 'wt_status_use_color') which _are_ declared, and are used by
builtin-commit.c. So maybe we'd like to export it at some point, but it's
not declared now, and not used outside of that file, so 'static' it is in
this patch.

6df514af9d format-patch: construct patch filename in one function
reopen_stdout() usually takes the oneline subject of a commit,
appends the patch suffix, prepends the output directory (if any) and
then reopens stdout as the resulting file. Now the patch filename (the
oneline subject and the patch suffix) is created in
get_patch_filename() and passed to reopen_stdout() which prepends the
output directory and reopens stdout as that file.

The original function to get the oneline description,
get_oneline_for_filename(), has been renamed to get_patch_filename() to
reflect its new functionality.

30984ed2e9 format-patch: support deep threading
For deep threading mode, i.e., the mode that gives a thread structured
like

  + [PATCH 0/n] Cover letter
   `-+ [PATCH 1/n] First patch
      `-+ [PATCH 2/n] Second patch
         `-+ ...

we currently have to use 'git send-email --thread' (the default).  On
the other hand, format-patch also has a --thread option which gives
shallow mode, i.e.,

  + [PATCH 0/n] Cover letter
  |-+ [PATCH 1/n] First patch
  |-+ [PATCH 2/n] Second patch
  ...

To reduce the confusion resulting from having two indentically named
features in different tools giving different results, let format-patch
take an optional argument '--thread=deep' that gives the same output
as 'send-mail --thread'.  With no argument, or 'shallow', behave as
before.  Also add a configuration variable format.thread with the same
semantics.

b079c50e03 format-patch: track several references
Currently, format-patch can only track a single reference (the
In-Reply-To:) for each mail.  To ensure proper threading, we should
list all known references for every mail.

Change the rev_info.ref_message_id field to a string_list, so that we
can append references at will, and change the output formatting
routines to print all of them in the References: header.  The last
entry in the list is implicitly assumed to be the In-Reply-To:, which
gives output consistent with RFC 2822:

   The "References:" field will contain the contents of the parent's
   "References:" field (if any) followed by the contents of the
   parent's "Message-ID:" field (if any).

Note that this is just preparatory work; nothing uses it yet, so all
"References:" fields in the output are still only one deep.

68c2ec7f43 format-patch: show patch text for the root commit
Even without --root specified, if the range given on the command line
happens to include a root commit, we should include its patch text in the

This fix deliberately ignores log.showroot configuration variable because
"format-patch" and "log -p" can and should behave differently in this
case, as the former is about exporting a part of your history in a form
that is replayable elsewhere and just giving the commit log message
without the patch text does not make any sense for that purpose.

Noticed and fix originally attempted by Nathan W. Panike; credit goes to
Alexander Potashev for injecting sanity to my initial (broken) fix that
used the value from log.showroot configuration, which was misguided.

5ec11af61d reorder ALLOW_TEXTCONV option setting
Right now for the diff porcelain and the log family, we
call:

  init_revisions();
  setup_revisions();
  DIFF_OPT_SET(ALLOW_TEXTCONV);

However, that means textconv will _always_ be on, instead of
being a default that can be manipulated with
setup_revisions. Instead, we want:

  init_revisions();
  DIFF_OPT_SET(ALLOW_TEXTCONV);
  setup_revisions();

which is what this patch does.

We'll go ahead and move the callsite in wt-status, also;
even though the user can't pass any options here, it is a
cleanup that will help avoid any surprise later if the
setup_revisions line is changed.

d467a525da Make '--decorate' set an explicit 'show_decorations' flag
We will want to add decorations without necessarily showing them, so add
an explicit revisions info flag as to whether we're showing decorations
or not.

0f3a290b89 Add a 'source' decorator for commits
We already support decorating commits by tags or branches that point to
them, but especially when we are looking at multiple branches together,
we sometimes want to see _how_ we reached a particular commit.

We can abuse the '->util' field in the commit to keep track of that as
we walk the commit lists, and get a reasonably useful view into which
branch or tag first reaches that commit.

Of course, if the commit is reachable through multiple sources (which is
common), our particular choice of "first" reachable is entirely random
and depends on the particular path we happened to follow.
