[PATCH] _git-push: complete remote branch names respecting --delete

["Øystein Walle" <oystwa@gmail.com>]

If you want to delete the branch foo from origin and type:

    git push --delete origin f<TAB>

it might get completed as:

    git push --delete origin origin/foo

which will lead Git into erroring out saying the remote ref doesn't
exist. If -d or --delete is given on the command line then complete
remote branches without their prefix, otherwise proceed as before.
