When doing a reflog walk, you can get some information about
the reflog (such as the subject line), but not the identity
information (i.e., name and email).
Let's make those available, mimicing the options for author
and committer identity.

The code paths for showing commits in "git log" and "git
rev-list --graph" correctly handle embedded NULs by looking
only at the resulting strbuf's length, and never treating it
as a C string. The code path for regular rev-list, however,
used printf("%s"), which resulted in truncated output. This
patch uses fwrite instead, like the --graph code path.

We have the '+' modifiier which helps combine format specifiers which
may possibly be empty, e.g. '%s%+b%n'.
Introduce an analogous ' ' (space) modifier which adds a space before
non-empty items. This helps assemble "one line type" format specifiers.

pretty: Respect --abbrev option
shortlog: Document and test --format option
t4201 (shortlog): Test output format with multiple authors
t4201 (shortlog): guard setup with test_expect_success
Documentation/shortlog: scripted users should not rely on implicit HEAD
Prior to this, the output of git log -1 --format=%h was always 7
characters long, without regard to whether --abbrev had been passed.

55246aa (Dont use "<unknown>" for placeholders and suppress printing
of empty user formats) introduced a check to prevent empty
user-formats from being printed. This test didn't take empty commit
messages into account, and prevented the line-termination from being
output. This lead to multiple commits on a single line.
Correct it by guarding the check with a check for user-format. A
similar correction for the --graph code-path has been included.

The only way to safely quote arbitrary text in a pretty-print user
format is to replace instances of "%" with "%x25". This is slightly
unreadable, and many users would expect "%%" to produce a single
"%", as that is what printf format specifiers do.
This patch converts "%%" to "%" for all users of strbuf_expand():
(1) git-daemon interpolated paths
(2) pretty-print user formats
(3) merge driver command lines
Case (1) was already doing the conversion itself outside of
strbuf_expand(). Case (2) is the intended beneficiary of this patch.
Case (3) users probably won't notice, but as this is user-facing
behavior, consistently providing the quoting mechanism makes sense.

Add three new --pretty=format escapes:
%gD long reflog descriptor (e.g. refs/stash@{0})
%gd short reflog descriptor (e.g. stash@{0})
%gs reflog message
This is achieved by passing down the reflog info, if any, inside the
pretty_print_context struct.
We use the newly refactored get_reflog_selector(), and give it some
extra functionality to extract a shortened ref. The shortening is
cached inside the commit_reflogs struct; the only allocation of it
happens in read_complete_reflog(), where it is initialised to 0. Also
add another helper get_reflog_message() for the message extraction.
Note that the --format="%h %gD: %gs" tests may not work in real
repositories, as the --pretty formatter doesn't know to leave away the
": " on the last commit in an incomplete (because git-gc removed the
old part) reflog. This equivalence is nevertheless the main goal of
this patch.
Thanks to Jeff King for reviews, the %gd testcase and documentation.

This teaches the "pretty" machinery to expand '%+x' to a LF followed by
the expansion of '%x' if and only if '%x' expands to a non-empty string,
and to remove LFs before '%-x' if '%x' expands to an empty string. This
works for any supported expansion placeholder 'x'.
This is expected to be immediately useful to reproduce the commit log
message with "%s%+b%n"; "%s%n%b%n" adds one extra LF if the log message is
a one-liner.

Currently, the only colors available to --pretty=format
users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.
Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:
git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'
to emulate --pretty=oneline, or even
git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'
if you want to relive the awesomeness of 4-color CGA.

When running a command like:
git log --pretty=format:%ad --date=short
the date option was ignored. This patch causes it to use whatever
format was specified by --date (or by --relative-date, etc), just
as the non-user formats would do.

As a general principle, we should not use "git diff" to validate the
results of what git command that is being tested has done. We would not
know if we are testing the command in question, or locating a bug in the
cute hack of "git diff --no-index".
Rather use test_cmp for that purpose.

When e-mail address is empty (e.g. "A U Thor <>"), --pretty=format
misparsed the commit header and did not pick up the date field correctly.
Noticed by Marco, fixed slightly differently with additional sanity
check and with a test.

This changes the interporate() to replace entries with NULL values
by the empty string, and uses it to interpolate missing fields in
custom format output used in git-log and friends. It is most useful
to avoid <unknown> output from %b format for a commit log message
that lack any body text.

There are two breakages in the %P/%p interpolation. It appended
an excess SP at the end of the list, and it gave uninitialized
contents of a buffer on the stack for root commits.
This fixes it, while updating the t6006 test which expected the
wrong output.
