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.

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.

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

To reduce the confusion resulting from having two indentically named
features in different tools giving different results, let format-patch

before. Also add a configuration variable format.thread with the same

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.

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
output.
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.

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.

Diffs that have been produced with textconv almost certainly
cannot be applied, so we want to be careful not to generate
them in things like format-patch.
This introduces a new diff options, ALLOW_TEXTCONV, which
controls this behavior. It is off by default, but is
explicitly turned on for the "log" family of commands, as
well as the "diff" porcelain (but not diff-* plumbing).
Because both text conversion and external diffing are
controlled by these diff options, we can get rid of the
"plumbing versus porcelain" distinction when reading the
config. This was an attempt to control the same thing, but
suffered from being too coarse-grained.

format-patch is most commonly used for multiple patches at once when
sending a patchset, in which case we want to number the patches; on
the other hand, single patches are not usually expected to be
numbered.
In other words, the typical behavior expected from format-patch is the
one obtained by enabling autonumber, so we set it to be the default.
Users that want to disable numbering for a particular patchset can do
so with the existing -N command-line switch. Users that want to
change the default behavior can use the format.numbering config key.

Previously, running "git format-patch -U5" would cause the
low-level diff machinery to change the diff output format
from "not specified" to "patch". This meant that
format-patch thought we explicitly specified a diff output
format, and would not use the default format. The resulting
message lacked both the diffstat and the summary, as well as
the separating "---".
Now format-patch explicitly checks for this condition and
uses the default. That means that "git format-patch -p" will
now have the "-p" ignored.
