When a submodule repository uses alternate object store mechanism, some
commands that were started from the superproject did not notice it and
failed with "No such object" errors.  The subcommands of "git submodule"
command that recursed into the submodule in a separate process were OK;
only the ones that cheated and peeked directly into the submodule's
repository from the primary process were affected.

The directory path used in "git diff --no-index", when it recurses

When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.

At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.

So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.

The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

From the FILES section of the git-config(1) manual:

	$GIT_DIR/config::
		Repository specific configuration file. (The filename is
		of course relative to the repository root, not the working
		directory.)

That's confusing because $GIT_DIR really is relative to the working
directory.

	$ GIT_DIR=.git GIT_EDITOR='pwd; echo editing'
	$ export GIT_DIR GIT_EDITOR
	$ git config --edit --local
	/home/jrn/src/git/Documentation
	editing .git/config

It turns out that the comment is a remnant from older days when the
heading said ".git/config" (which is indeed relative to the top of the
worktree).

It was only when the heading was changed to refer more precisely to
<git dir>/config (see v1.5.3.2~18, AsciiDoc tweak to avoid leading
dot, 2007-09-14) that the parenthesis stopped making sense.  Remove
it.

"git status --porcelain" ignored "--branch" option by mistake.  The output
for "git status --branch -z" was also incorrect and did not terminate the

The default compiler and cflags were mostly "works for me"
when I built the original version. We need to be much less
careful here than usual, because we know we are building
only on OS X.  But it's only polite to at least respect the
CFLAGS and CC definitions that the user may have provided
earlier.

While we're at it, let's update our definitions and rules to
be more like the top-level Makefile; default our CFLAGS to
include -O2, and make sure we use CFLAGS and LDFLAGS when
linking.

  t3404: begin "exchange commits with -p" test with correct preconditions

We fairly consistently say "superproject" and never "supermodule" these
days. But there are seven occurrences of "supermodule" left in the current
work tree. Three appear in Release Notes for 1.5.3 and 1.7.7, three in
test names and one in a C-code comment.

Replace all occurrences of "supermodule" outside of the Release Notes
(which shouldn't be changed after the fact) with "superproject" for
consistency.

The test case shows a bug in 'rebase -p', but even if the bug were fixed
the test would fail because it did not ensure that the preconditions match
the postconditions that were checked. Insert the suitable 'git checkout'.

The test intends to rebase a branchy history onto a later commit, but it
forgot to reset HEAD back to an earlier commit before it set up the side
branches. In the end, every "rebased" commit was only a fast-forward and
the 'rebase -p' did not change the commit graph at all. Insert the missing
checkout that moves to an earlier commit.

The description was misleading because it lead the reader to believe
that --git-dir would always show a relative path when, in fact, the
actual behaviour does not guarantee this.

Rather, it was intended that the advice be given that if a relative
path is shown, then the path is relative to the current working
directory and not some other directory (for example, the root of the
working tree).

The documentation of the dcommit subcommand is reworded to clarify that
the optional argument refers to a git branch, not an SVN branch.

The discussion of the optional argument is put into its own paragraph
as is the guidance about using 'dcommit' in preference to 'set-tree'.

The section on REBASE vs. PULL/MERGE is reworded to incorporate the
advice to prefer 'git rebase' previously in the description of 'dcommit'.

When git svn rebase is performed after an unpushed merge, the
rebase operation follows both parents and replays both the user's
local commits and those from the merged branch. This is usually
not the intended behavior.
This patch adds support for the --preserve-merges/-p flag which
allows for a better workflow by re-applying merge commits as merges.

Commit 875b91b3 (diff --no-index: use strbuf for temporary pathnames,
2012-04-25) introduced a regression when using diff --no-index with
directories.  When iterating through a directory, the switch to strbuf
from heap-allocated char arrays caused paths to form like 'dir/file1',
'dir/file1file2', rather than 'dir/file1', 'dir/file2' as expected.

Avoid this by resetting the paths variables to their original length
before each iteration.
