8d81408435 git-send-email: add --transfer-encoding option
The thread at http://thread.gmane.org/gmane.comp.version-control.git/257392
details problems when applying patches with "git am" in a repository with
CRLF line endings.  In the example in the thread, the repository originated
from "git-svn" so it is not possible to use core.eol and friends on it.

Right now, the best option is to use "git am --keep-cr".  However, when
a patch create new files, the patch application process will reject the
new file because it finds a "/dev/null\r" string instead of "/dev/null".

The problem is that SMTP transport is CRLF-unsafe.  Sending a patch by
email is the same as passing it through "dos2unix | unix2dos".  The newly
introduced CRLFs are normally transparent because git-am strips them. The
keepcr=true setting preserves them, but it is mostly working by chance
and it would be very problematic to have a "git am" workflow in a
repository with mixed LF and CRLF line endings.

The MIME solution to this is the quoted-printable transfer enconding.
This is not something that we want to enable by default, since it makes
received emails horrible to look at.  However, it is a very good match
for projects that store CRLF line endings in the repository.

The only disadvantage of quoted-printable is that quoted-printable
patches fail to apply if the maintainer uses "git am --keep-cr".  This
is because the decoded patch will have two carriage returns at the end
of the line.  Therefore, add support for base64 transfer encoding too,
which makes received emails downright impossible to look at outside
a MUA, but really just works.

The patch covers all bases, including users that still live in the late
80s, by also providing a 7bit content transfer encoding that refuses
to send emails with non-ASCII character in them.  And finally, "8bit"
will add a Content-Transfer-Encoding header but otherwise do nothing.

251e7dad51 diff-highlight: exit when a pipe is broken
While using diff-highlight with other tools, I have discovered that Python
ignores SIGPIPE by default.  Unfortunately, this also means that tools
attempting to launch a pager under Python--and don't realize this is
happening--means that the subprocess inherits this setting.  In this case, it
means diff-highlight will be launched with SIGPIPE being ignored.  Let's work
with those broken scripts by restoring the default SIGPIPE handler.

8f7ff5b2fe completion: silence "fatal: Not a git repository" error
It is possible that a user is trying to run a git command and fail
to realize that they are not in a git repository or working tree.
When trying to complete an operation, __git_refs would fall to a
degenerate case and attempt to use "git for-each-ref", which would
emit the error.

Hide this error message coming from "git for-each-ref".

fca416a41e completion: use "git -C $there" instead of (cd $there && git ...)
We have had "git -C $there" to first go to a different directory
and run a Git command without changing the arguments for quite some
time.  Use it instead of (cd $there && git ...) in the completion
script.

This allows us to lose the work-around for misfeatures of modern
interactive-minded shells that make "cd" unusable in scripts (e.g.
end users' $CDPATH taking us to unexpected places in any POSIX
shell, and chpwd functions spewing unwanted output in zsh).

Based on Øystein Walle's idea, which was raised during the
discussion on the solution by Brandon Turner for a problem zsh users
had with RVM which mucks with chpwd_functions in users' environments
(https://github.com/wayneeseguin/rvm/issues/3076).

As $root variable, which is used to direct where to chdir to, is set
to "." based on if $2 to __git_index_files is set (not if it is empty),
the only caller of the function is fixed not to pass the optional $2
when it does not want us to switch to a different directory.  Otherwise
we would end up doing "git -C '' command...", which would not work.

Maybe we would want "git -C '' command..." to mean "do not chdir
anywhere", but that is a spearate topic.

0fa7f01635 git-prompt: do not look for refs/stash in $GIT_DIR
Since dd0b72c (bash prompt: use bash builtins to check stash
state, 2011-04-01), git-prompt checks whether we have a
stash by looking for $GIT_DIR/refs/stash. Generally external
programs should never do this, because they would miss
packed-refs.

That commit claims that packed-refs does not pack
refs/stash, but that is not quite true. It does pack the
ref, but due to a bug, fails to prune the ref. When we fix
that bug, we would want to be doing the right thing here.

960160b061 subtree: make "all" default target of Makefile
You should be able to run "make" in contrib/subtree with no
arguments and get the "all" target. This was broken by 8e2a5cc
(contrib/subtree/Makefile: use GIT-VERSION-FILE, 2014-05-06), which
put the rule for GIT-VERSION-FILE higher in the file.

We can fix this by putting an empty "all::" target at the top of the
file, just like our main Makefile does, and document that fact.
That fixes this instance and future-proofs against it happening
again.

56f24e80f0 completion: handle '!f() { ... }; f' and "!sh -c '...' -" aliases
'!f() { ... }; f' and "!sh -c '....' -" are recommended patterns for
declaring more complex aliases (see git wiki [1]).  This commit teaches
the completion to handle them.

When determining which completion to use for an alias, an opening brace
or single quote is now skipped, and the search for a git command is
continued.  For example, the aliases '!f() { git commit ... }' or "!sh
-c 'git commit ...'" now trigger commit completion.  Previously, the
search stopped on the opening brace or quote, and the completion tried
it to determine how to complete, which obviously was useless.

The null command ':' is now skipped, so that it can be used as
a workaround to declare the desired completion style.

For example, the aliases

    !f() { : git commit ; if ... } f
    !sh -c ': git commit; if ...' -

now trigger commit completion.

Shell function declarations now work with or without space before
the parens, i.e. '!f() ...' and '!f () ...' both work.
