[RFC] deprecate git stash save? (was: Re: [PATCH 2/3] http-push: fix construction of hex value from path)

Since you were asking :)  With the introduction of 'git stash push',
my hope was always that we could eventually get rid of 'git stash
save' and only keep one interface around.

As there still many references to it around on the internet, it
probably requires a bit of a longer deprecation plan.  What do you
think about the following:

- Change docs/man pages to use 'git stash push' everywhere instead of
  'git stash save'.
- Mention the deprecation in the release notes and in the man page.
- Print a warning when 'git stash save' is used.
- Eventually get rid of it (maybe something for 3.0?)

The steps above would all occur sequentially with a few releases
between each of them.

A patch for the first step below.  I think that even makes sense if we
don't want to follow through with the deprecation.

Subject: [PATCH] replace git stash save with git stash push in the documentation

git stash push is the newer interface for creating a stash.  While we
are still keeping git stash save around for the time being, it's better
to point new users of git stash to the more modern (and more feature
rich) interface, instead of teaching them the older version that we
might want to phase out in the future.
