If an empty message is specified with the option -m of git commit then
the editor is started. That's unexpected and unnecessary. Instead of
using the length of the message string for checking if the user
specified one, directly remember if the option -m was given.

Currently, git will append two newlines to every message supplied via
the -m switch. The purpose of this is to allow -m to be supplied
multiple times and have each supplied string become a paragraph in the
resulting commit message.
Normally, this does not cause a problem since any trailing newlines will
be removed by the cleanup operation. If cleanup=verbatim for example,
then the trailing newlines will not be removed and will survive into the
resulting commit message.
Instead, let's ensure that the string supplied to -m is newline terminated,
but only append a second newline when appending additional messages.

The logmsg_reencode function will return the reencoded
commit buffer, or NULL if reencoding failed or no reencoding
was necessary. Since every caller then ends up checking for NULL
and just using the commit's original buffer, anyway, we can
be a bit more helpful and just return that buffer when we
would have returned NULL.
Since the resulting string may or may not need to be freed,
we introduce a logmsg_free, which checks whether the buffer
came from the commit object or not (callers either
implemented the same check already, or kept two separate
pointers, one to mark the buffer to be used, and one for the
to-be-freed string).
Pushing this logic into logmsg_* simplifies the callers, and
will let future patches lazily load the commit buffer in a
single place.

When git-commit is asked to reuse a commit message via "-c",
we call read_commit_message, which looks up the commit and
hands back either the re-encoded result, or a copy of the
original. We make a copy in the latter case so that the
ownership semantics of the return value are clear (in either
case, it can be freed).
However, since we return a "const char *", and since the
resulting buffer's lifetime is the same as that of the whole
program, we never bother to free it at all.
Let's just drop the copy. That saves us a copy in the common
case. While it does mean we leak in the re-encode case, it
doesn't matter, since we are relying on program exit to free
the memory anyway.

Create find_hook() function to determine if a given hook exists and is
executable. If it is, the path to the script will be returned,
otherwise NULL is returned.
This encapsulates the tests that are used to check for the existence of
a hook in one place, making it easier to modify those checks if that is
found to be necessary. This also makes it simple for places that can
use a hook to check if a hook exists before doing, possibly lengthy,
setup work which would be pointless if no such hook is present.
The returned value is left as a static value from get_pathname() rather
than a duplicate because it is anticipated that the return value will
either be used as a boolean, immediately added to an argv_array list
which would result in it being duplicated at that point, or used to
actually run the command without much intervening work. Callers which

We keep track of whether the user ident was given to us
explicitly, or if we guessed at it from system parameters
like username and hostname. However, we kept only a single
variable. This covers the common cases (because the author
and committer will usually come from the same explicit
source), but can miss two cases:
1. GIT_COMMITTER_* is set explicitly, but we fallback for
GIT_AUTHOR. We claim the ident is explicit, even though
the author is not.
2. GIT_AUTHOR_* is set and we ask for author ident, but
not committer ident. We will claim the ident is
implicit, even though it is explicit.
This patch uses two variables instead of one, updates both
when we set the "fallback" values, and updates them
individually when we read from the environment.
Rather than keep user_ident_sufficiently_given as a
compatibility wrapper, we update the only two callers to
check the committer_ident, which matches their intent and
what was happening already.

You can currently set the output format to --short or
--porcelain. There is no --long, because we default to it
already. However, you may want to override an alias that
uses "--short" to get back to the default.
This requires a little bit of refactoring, because currently
we use STATUS_FORMAT_LONG internally to mean the same as
"the user did not specify anything". By expanding the enum
to include STATUS_FORMAT_NONE, we can distinguish between
the implicit and explicit cases. This effects these
conditions:
1. The user has asked for NUL termination. With NONE, we
currently default to turning on the porcelain mode.
With an explicit --long, we would in theory use NUL
termination with the long mode, but it does not support
it. So we can just complain and die.
2. When an output format is given to "git commit", we
default to "--dry-run". This behavior would now kick in
when "--long" is given, too.

The identity of the committer will ultimately be pulled from
the ident code by commit_tree(). However, we make an attempt
to check the author and committer identity early, before the
user has done any manual work like inputting a commit
message. That lets us abort without them having to worry
about salvaging the work from .git/COMMIT_EDITMSG.
The early check for committer ident does not use the
IDENT_STRICT flag, meaning that it would not find an empty
name field. The motivation was presumably because we did not
want to be too restrictive, as later calls might be more lax
(for example, when we create the reflog entry, we do not
care too much about a real name). However, because
commit_tree will always get a strict identity to put in the
commit object itself, there is no point in being lax only to
die later (and in fact it is harmful, because the user will
have wasted time typing their commit message).
Incidentally, this bug was masked prior to 060d4bb, as the
initial loose call would taint the later strict call. So the
commit would succeed (albeit with a bogus committer line in
the commit object), and nobody noticed that our early check
did not match the later one.

The current code reads the config and command-line options
into a separate "colopts" variable, and then copies the
contents of that variable into the "struct wt_status". We
can eliminate the extra variable and copy just write
straight into the wt_status struct.
This simplifies the "status" code a little bit.
Unfortunately, it makes the "commit" code one line more
complex; a side effect of the separate variable was that
"commit" did not copy the colopts variable, so any
column.status configuration had no effect.
The result still ends up cleaner, though. In the previous
version, it was unclear whether commit simply forgot to copy
the colopt variable, or whether it was intentional. Now it
explicitly turns off column options. Furthermore, if commit
later learns to respect column.status, this will make the
end result simpler. I punted on just adding that feature
now, because it was sufficiently non-obvious that it should
not go into a refactoring patch.

In prepare_index(), we refresh the index, and then write it to disk if

The lines of GPG detached signature are placed in a new multi-line header
field, instead of tucking the signature block at the end of the commit log
message text (similar to how signed tag is done), for multiple reasons:
- The signature won't clutter output from "git log" and friends if it is
in the extra header. If we place it at the end of the log message, we
would need to teach "git log" and friends to strip the signature block
with an option.
- Teaching new versions of "git log" and "gitk" to optionally verify and
show signatures is cleaner if we structurally know where the signature
block is (instead of scanning in the commit log message).
- The signature needs to be stripped upon various commit rewriting
operations, e.g. rebase, filter-branch, etc. They all already ignore
unknown headers, but if we place signature in the log message, all of
these tools (and third-party tools) also need to learn how a signature
block would look like.
- When we added the optional encoding header, all the tools (both in tree
and third-party) that acts on the raw commit object should have been
fixed to ignore headers they do not understand, so it is not like that
new header would be more likely to break than extra text in the commit.
A commit made with the above sample sequence would look like this:

A commit header that has a multi-line payload begins with the header tag

the remaining lines have a SP inserted at the beginning.

All of the "do we want color" flags default to -1 to
indicate that we don't have any color configured. This value
is handled in one of two ways:
1. In porcelain, we check early on whether the value is
still -1 after reading the config, and set it to the
value of color.ui (which defaults to 0).
2. In plumbing, it stays untouched as -1, and want_color
defaults it to off.
This works fine, but means that every porcelain has to check
and reassign its color flag. Now that want_color gives us a
place to put this check in a single spot, we can do that,
simplifying the calling code.

The file-scope global variable head_sha1[] was used to hold the object
name of the current HEAD commit (unless we are about to make an initial
commit). Also there is an independent "static int initial_commit".
Fix all the functions on the call-chain that use these two variables to
take a new "(const) struct commit *current_head" argument instead, and
replace their uses, e.g. "if (initial_commit)" becomes "if (!current_head)"
and a reference to "head_sha1" becomes "current_head->object.sha1".
