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.

When we abort a rebase, we return to the original value of
HEAD. Failing to write a reflog entry means we create a
gap in the reflog (which can cause "git show
HEAD@{5.minutes.ago}" to issue a warning). Plus having the
extra entry makes the reflog easier to follow for a human.

Recent versions of asciidoc will treat "->" as a
single-glyph arrow symbol, unless it is inside a literal
code block. This is a problem if we are discussing literal
output and want to show the ASCII characters.
Our usage falls into three categories:
1. Inside a code block. These can be left as-is.
2. Discussing literal output or code, but inside a
paragraph. This patch escapes these as "\->".
3. Using the arrow as a symbolic element, such as "use the
Edit->Account Settings menu". In this case, the
arrow symbol is preferable, so we leave it as-is.

The --porcelain format was originally identical to the
--short format, but designed to be stable as the short
format changed. Since this was written, the short format
picked up a few incompatible niceties, but this description
was never changed.

some sub-section headings to make the "output" section a

In older versions of git, we used rfc822 header folding to
indicate that the original subject line had multiple lines
in it. But since a1f6baa (format-patch: wrap long header
lines, 2011-02-23), we now use header folding whenever there
is a long line.
This means that "git am" cannot trust header folding as a
sign from format-patch that newlines should be preserved.
Instead, format-patch needs to signal more explicitly that
the newlines are significant. This patch does so by
rfc2047-encoding the newlines in the subject line. No
changes are needed on the "git am" end; it already decodes
the newlines properly.

We have a pretty_print_context representing the parameters
for a pretty-print session, but we did not use it uniformly.
As a result, functions kept growing more and more arguments.
Let's clean this up in a few ways:
1. All pretty-print pp_* functions now take a context.
This lets us reduce the number of arguments to these
functions, since we were just passing around the
context values separately.
2. The context argument now has a cmit_fmt field, which
was passed around separately. That's one less argument
per function.
3. The context argument always comes first, which makes
calling a little more uniform.
This drops lines from some callers, and adds lines in a few
places (because we need an extra line to set the context's
fmt field). Overall, we don't save many lines, but the lines
that are there are a lot simpler and more readable.

Some shells interpret '(( ))' according to the rules for arithmetic
expansion. This may not follow POSIX, but is prevalent in commonly used
shells. Bash does not have a problem with this particular instance of
'((', likely because it is not followed by a '))', but the public domain
ksh does, and so does ksh on IRIX 6.5.
So, add a space between the parenthesis to avoid confusing these shells.

Without the "-k" option, mailinfo will convert a folded
subject header like:
Subject: this is a
subject that doesn't
fit on one line
into a single line. With "-k", however, we assumed that
these newlines were significant and represented something
that the sending side would want us to preserve.
For messages created by format-patch, this assumption was
broken by a1f6baa (format-patch: wrap long header lines,
2011-02-23). For messages sent by arbitrary MUAs, this was
probably never a good assumption to make, as they may have
been folding subjects in accordance with rfc822's line
length recommendations all along.
This patch now joins folded lines with a single whitespace
character. This treats header folding purely as a syntactic
feature of the transport mechanism, not as something that
format-patch is trying to tell us about the original
subject.

Commit a1f6baa (format-patch: wrap long header lines,
2011-02-23) changed format-patch's behavior with respect to
long header lines, but made no accompanying changes to the
receiving side. It was thought that "git am" would handle
these folded subjects fine, but there is a regression when
using "am -k".
Let's add a test documenting this. While we're at it, let's
give more complete test coverage to document what should be
happening in each case. We test three types of subjects:
a short one, one long enough to require wrapping, and a
multiline subject. For each, we test these three
combinations:
format-patch | am
format-patch -k | am
format-patch -k | am -k
We don't bother testing "format-patch | am -k", which is
nonsense (you will be adding in [PATCH] cruft to each
subject).
This reveals the regression above (long subjects have
linebreaks introduced via "format-patch -k | am -k"),
as well as an existing non-optimal behavior (multiline
subjects are not preserved using "-k").

The read_in_full function repeatedly calls read() to fill a
buffer. If the first read() returns an error, we notify the
caller by returning the error. However, if we read some data
and then get an error on a subsequent read, we simply return
the amount of data that we did read, and the caller is
unaware of the error.
This makes the tradeoff that seeing the partial data is more
important than the fact that an error occurred. In practice,
this is generally not the case; we care more if an error
occurred, and should throw away any partial data.
I audited the current callers. In most cases, this will make
no difference at all, as they do:
if (read_in_full(fd, buf, size) != size)
error("short read");
However, it will help in a few cases:
1. In sha1_file.c:index_stream, we would fail to notice
errors in the incoming stream.
2. When reading symbolic refs in resolve_ref, we would
fail to notice errors and potentially use a truncated
ref name.
3. In various places, we will get much better error
messages. For example, callers of safe_read would
erroneously print "the remote end hung up unexpectedly"
instead of showing the read error.

Commit 13fc2c1 (remote: disallow some nonsensical option
combinations, 2011-03-30) made it impossible to use "remote
add -t foo --mirror". The argument was that specifying
specific branches is useless because:
1. Push mirrors do not want a refspec at all.
2. The point of fetch mirroring is to use a broad refspec
like "refs/*", but using "-t" overrides that.
Point (1) is valid; "-t" with push mirrors is useless. But
point (2) ignored another side effect of using --mirror: it
fetches the refs directly into the refs/ namespace as they
are found upstream, instead of placing them in a
separate-remote layout.
So 13fc2c1 was overly constrictive, and disallowed
reasonable specific-branch mirroring, like:
git remote add -t heads/foo -t heads/bar --mirror=fetch
which makes the local "foo" and "bar" branches direct
mirrors of the remote, but does not fetch anything else.
This patch restores the original behavior, but only for
fetch mirrors.

Somebody tried to compile fnmatch.c compatibility file on Interix and got
an error because no header included in the file on that platform defined
NULL. It usually comes from stddef.h and indirectly from other headers
like string.h, unistd.h, stdio.h, stdlib.h, etc., but with the way we
compile this file from our Makefile, inclusion of the header files that
are expected to define NULL in fnmatch.c do not happen because they are
protected with "#ifdef STDC_HEADERS", etc. which we do not pass.
As the least-impact workaround, give a fall-back definition when none of
the headers define NULL.
