Subject: stash: introduce push verb

Introduce a new git stash push verb in addition to git stash save.  The
push verb is used to transition from the current command line arguments
to a more conventional way, in which the message is given as an argument
to the -m option.

This allows us to have pathspecs at the end of the command line
arguments like other Git commands do, so that the user can say which
subset of paths to stash (and leave others behind).

Subject: stash: add test for the create command line arguments

Currently there is no test showing the expected behaviour of git stash
create's command line arguments.  Add a test for that to show the
current expected behaviour and to make sure future refactorings don't
break those expectations.

Subject: stash: refactor stash_create

Refactor the internal stash_create function to use a -m flag for
specifying the message and -u flag to indicate whether untracked files
should be added to the stash.

This makes it easier to pass a pathspec argument to stash_create in the
next patch.

The user interface for git stash create stays the same.

Subject: stash: teach 'push' (and 'create_stash') to honor pathspec

While working on a repository, it's often helpful to stash the changes
of a single or multiple files, and leave others alone.  Unfortunately
git currently offers no such option.  git stash -p can be used to work
around this, but it's often impractical when there are a lot of changes
over multiple files.

Allow 'git stash push' to take pathspec to specify which paths to stash.

Subject: stash: use stash_push for no verb form

Now that we have stash_push, which accepts pathspec arguments, use
it instead of stash_save in git stash without any additional verbs.

Previously we allowed git stash -- -message, which is no longer allowed
after this patch.  Messages starting with a hyphen was allowed since
3c2eb80f, ("stash: simplify defaulting to "save" and reject unknown
options").  However it was never the intent to allow that, but rather it
was allowed accidentally.

Subject: stash: allow pathspecs in the no verb form

Now that stash_push is used in the no verb form of stash, allow
specifying the command line for this form as well.  Always use -- to
disambiguate pathspecs from other non-option arguments.

Also make git stash -p an alias for git stash push -p.  This allows
users to use git stash -p <pathspec>.
