If we encounter a symref that is dangling, in most cases we will warn
about it. The one exception is a dangling HEAD, as that indicates a
branch yet to be born.
However, the check in dwim_ref was not quite right. If we were fed
something like "HEAD^0" we would try to resolve "HEAD", see that it is
dangling, and then check whether the _original_ string we got was
"HEAD" (which it wasn't in this case). And that makes no sense; the
dangling thing we found was not "HEAD^0" but rather "HEAD".
Fixing this squelches a scary warning from "submodule summary HEAD" (and
consequently "git status" with status.submodulesummary set) in an empty
repo, as the submodule script calls "git rev-parse -q --verify HEAD^0".

The 'git stash pop' option parsing used to remove the first argument
in --index mode. At the time this was implemented, this first
argument was always --index. However, since the invention of the -q
option in fcdd0e9 (stash: teach quiet option, 2009-06-17) you can
cause an internal invocation of
git stash drop --index
by running
git stash pop -q --index
which then of course fails because drop doesn't know --index.
To handle this, instead let 'git stash apply' decide what the future
argument to 'drop' should be.
Warning: this means that 'git stash apply' must parse all options that
'drop' can take, and deal with them in the same way. This is
currently true for its only option -q.

The original patch that became cfe370c (grep: do not segfault when -f is
used, 2009-10-16), was made against "maint" or newer branch back then, but
the fix addressed the issue that was present as far as in 1.6.4 series.
The maintainer backported the patch to the 1.6.4 maintenance branch, but
failed to notice that the new tests assumed the setup done by the script
in "maint", which did quite a lot more than the same test script in 1.6.4
series, and the output didn't match the expected result.
This should fix it.

Newcomers to git that want to remove from the index only the
files that have disappeared from the working tree will probably
look for a way to do that in the documentation for 'git rm'.
Therefore, describe how that can be done (even though it involves
other commands than 'git rm'). Based on a suggestion by Junio,
but re-arranged and rewritten to better fit into the style of
command reference.
While at it, change a single occurrence of "work tree" to "working
tree" for consistency.

Commit 952dfc6 tried to tighten the safety valves for doing
a "reset --hard" in a bare repository or outside the work
tree, but accidentally broke the case for GIT_WORK_TREE.
This patch unbreaks it.
Most git commands which need a work tree simply use
NEED_WORK_TREE in git.c to die before they get to their
cmd_* function. Reset, however, only needs a work tree in
some cases, and so must handle the work tree itself. The
error that 952dfc6 made was to simply forbid certain
operations if the work tree was not set up; instead, we need
to do the same thing that NEED_WORK_TREE does, which is to
call setup_work_tree(). We no longer have to worry about dying
in the non-worktree case, as setup_work_tree handles that
for us.

--allow-empty ok to record an empty change
--cleanup <default> how to strip spaces and #comments from message
This is confusing, in part because it makes it ambiguous whether
--allow-empty, just above, refers to an empty diff or an empty message.
Move --cleanup into the 'message options' group. Also add a pair of

If the user's configured editor is emacsclient, the editor
will fail to launch if emacs is not running and the git
command that tried to lanuch the editor will abort. For most
commands, all you have to do is to start emacs and repeat
the command.
The "git rebase -i" command, however, aborts without cleaning
the "$GIT_DIR/rebase-merge" directory if it fails to launch the
editor, so you'll need to do "git rebase --abort" before
repeating the rebase command.
Change "git rebase -i" to terminate using "die_abort" (instead of
with "die") if the initial launch of the editor fails.

If a command is run with an absolute path as a pathspec inside a bare
repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen()
on NULL, which is the result of get_git_work_tree(), and segfaulted. It
should just fail instead.
Currently the function returns NULL even inside .git/ in a repository
with a work tree, but that is a separate issue.

When parsing the config file, if there is a value that is
syntactically correct but unused, we generally ignore it.
This lets non-core porcelains store arbitrary information in
the config file, and it means that configuration files can
be shared between new and old versions of git (the old
versions might simply ignore certain configuration).
The one exception to this is color configuration; if we
encounter a color.{diff,branch,status}.$slot variable, we
die if it is not one of the recognized slots (presumably as
a safety valve for user misconfiguration). This behavior
has existed since 801235c (diff --color: use
$GIT_DIR/config, 2006-06-24), but hasn't yet caused a
problem. No porcelain has wanted to store extra colors, and
we once a color area (like color.diff) has been introduced,
we've never changed the set of color slots.
However, that changed recently with the addition of
color.diff.func. Now a user with color.diff.func in their
config can no longer freely switch between v1.6.6 and older
versions; the old versions will complain about the existence
of the variable.
This patch loosens the check to match the rest of
git-config; unknown color slots are simply ignored. This
doesn't fix this particular problem, as the older version
(without this patch) is the problem, but it at least
prevents it from happening again in the future.

If a given command is not found, then help.c tries to guess which one the
user could have meant. If help.autocorrect is 0 or unset, then a list of
suggestions is given as long as the dissimilarity between the given command
and the candidates is not excessively high. But if help.autocorrect was
non-zero (i.e., a delay after which the command is run automatically), the
latter restriction on dissimilarity was not obeyed.
In my case, this happened:
$ git ..daab02
WARNING: You called a Git command named '..daab02', which does not exist.

Giving --format from the command line, or using output file extention to
DWIM the output format, with a pathspec that is disambiguated with an
explicit double-dash on the command line, e.g.
git archive -o file --format=zip HEAD -- path
git archive -o file.zip HEAD -- path
didn't work correctly.
This was because the code reordered (when one was given) or added (when
the format was inferred) a --format argument at the end, effectively
making it to "archive HEAD -- path --format=zip", i.e. an extra pathspec
that is unlikely to match anything.
The command line argument list should always be "options, revs and then
paths", and we should set a good example by inserting the --format at the
beginning instead.
