[PATCH] push: Allow @ shortcut with git-push

[PATCH] push: Allow @ shortcut with git-push

[Tomo Krajina]

Until now, HEAD could be used with git-push to push the current
branch. Now @ is a shortcut to HEAD, but it didn't work when
pushing branches. It fails with:

  fatal: remote part of refspec is not a valid name in @

Reinterpret all branch names from argv in order for @ to be used
when pushing branches.

I don't think this is the right way to go. There are many places where HEAD
cannot be replaced with @, or @{u}, or any of such syntaxes.

We might want to do this kind of replacement in many other places, but we would
need to make sure it makes sense.

Moreover, in order for this patch to be considered you need to add tests.

Cheers.
