The traverse_commit_list() API takes two callback functions, one to show
commit objects, and the other to show other kinds of objects. Even though
the former has a callback data parameter, so that the callback does not
have to rely on global state, the latter does not.

Give the show_objects() callback the same callback data parameter.

Allocating and then immediately freeing temporary memory a million times
when listing a million objects is distasteful.

There are two copies of traverse_commit_list callback that show the object
name followed by pathname the object was found, to produce output similar
to "rev-list --objects".

Unify them.

The callback to traverse_commit_list() are to take linked name_path and
a string for the last path component.

If the callee used its parameters, it would have seen duplicated leading
paths. In this particular case, the callee does not use this argument but
that is not a reason to leave the call broken.

Commit 8f323c00 (drop support for GIT_CONFIG_NOGLOBAL, 15-03-2011)
removed the git_config_global() function, among other things, since
it is no longer required. Unfortunately, this function has since
been unintentionally restored by a faulty conflict resolution.

Remove it.

to avoid being treated as delimiters for bold text, but these two were

If you give a zero-length subject prefix to format-patch
(e.g., "format-patch --subject-prefix="), we will print the
ugly:

  Subject: [ 1/2] your subject here

because we always insert a space between the prefix and
numbering. Requiring the user to provide the space in their
prefix would be more flexible, but would break existing
usage. This patch provides a DWIM and suppresses the space
for zero-length prefixes, under the assumption that nobody
actually wants "[ 1/2]".

Change the documentation for the git-sh-i18n--envsubst program to
include a SYNOPSIS section. Include the invocation of the program from
git-sh-i18n.sh.

Not having a SYNOPSIS section caused the "doc" target to fail on
Centos 5.5 with asciidoc 8.2.5, while building with 8.6.4 on Debian
works just fine.

The relevant error was:

Brian Gernhardt reported that test 'git grep -E -F -G a\\+b' fails on
OS X 10.6.7. This is because I assumed \+ is part of BRE, which isn't
true on all platforms.

The easiest way to make this test pass is to just update expected
output, but that would make the test pointless. Its real purpose is to
check whether 'git grep -E -F -G' is different from 'git grep -E -G -F'.
To check that, let's change pattern to "a+b*c". This should return
different match for -G, -F and -E.

I also made two small tweaks to the tests. First, I added path "ab" to
all calls to future-proof tests. Second, I updated last two tests to
better show that 'git grep -P -E' is different from 'git grep -E -P'.

The previous commit simply hijacked --quiet and essentially made it into a

When we finish a rebase, our detached HEAD is at the final
result. We update the original branch ref with this result,
and then point the HEAD symbolic ref at the updated branch.
We write a reflog for the branch update, but not for the
update of HEAD.

Because we're already at the final result on the detached
HEAD, moving to the branch actually doesn't change our
commit sha1 at all. So in that sense, a reflog entry would
be pointless.

However, humans do read reflogs, and an entry saying "rebase
finished: returning to refs/heads/master" can be helpful in
understanding what is going on.
