for-each-ref: introduce %(upstream:track[short])

Introduce %(upstream:track) to display "[ahead M, behind N]" and
%(upstream:trackshort) to display "=", ">", "<", or "<>"
appropriately (inspired by contrib/completion/git-prompt.sh).

Now you can use the following format in for-each-ref:

  %(refname:short)%(upstream:trackshort)

to display refs with terse tracking information.

Note that :track and :trackshort only work with "upstream", and error
out when used with anything else.

for-each-ref: introduce %(color:...) for color

Enhance 'git for-each-ref' with color formatting options.  You can now
use the following format in for-each-ref:

  %(color:green)%(refname:short)%(color:reset)

where color names are described in color.branch.*.

for-each-ref: avoid color leakage

To make sure that an invocation like the following doesn't leak color,

  $ git for-each-ref --format='%(subject)%(color:green)'

auto-reset at the end of the format string when the last color token
seen in the format string isn't a color-reset.

Merge branch 'jc/format-patch' into pu

A new option to send a single patch to the standard output to be
appended at the bottom of a message.  I personally have no need for
this, but it was easy enough to cobble together.  Tests, docs and
stripping out more MIMEy stuff are left as exercises to interested
parties.

Merge branch 'jt/commit-fixes-footer' into pu

There is an ongoing discussion around this topic; in general I am
fairly negative on a new feature that is too narrow and prefer a
more generic solution that can be tailored for specific needs, as
many people stated in the thread.

It appears that the discussion stalled.

Merge branch 'cn/thin-push-capability' into pu

Peff had a good suggestion to control this by expressing what the

by Shawn, too.

* cn/thin-push-capability:
  send-pack: only send a thin pack if the server supports it

commit -v: strip diffs and submodule shortlogs from the commit message

When using the '-v' option of "git commit", the diff added to the commit
message temporarily for editing is stripped off after the user exited the
editor by searching for "\ndiff --git " and truncating the commmit message
there if it is found.

But this approach has two problems.

 - when the commit message itself contains a line starting with
   "diff --git" it will be truncated there prematurely; and

  - when the "diff.submodule" setting is set to "log", the diff may
    start with "Submodule <hash1>..<hash2>", which will be left in
    the commit message while it shouldn't.

Fix that by introducing a special scissor separator line starting
with the comment character '#' followed by a line describing what it
is for.  The scissor line - which will not be translated - is used
to reliably detect the start of the diff so it can be chopped off
from the commit message, no matter what the user enters there.

Turn a known test failure fixed by this change into a successful
test and add another one for a diff starting with a submodule log.
