Refspecs without a source side have been reported as confusing by many.
As an alternative, this adds support for commands like:
git push origin --delete somebranch
Specifically, --delete will prepend a colon to all colon-less refspecs
given on the command line, and will refuse to accept refspecs with
colons to prevent undue confusion.

All good points, and I actually remembered to catch the colon-refspec
case a few minutes after sending the patch, but didn't have time to fix
it up. (Sorry for not considering the old thread; I had gotten
unsubscribed from the list back then).
I think with this change it becomes much saner. And no, I'm not
proposing to add --rename and --copy, too. ;)
The new error message is not completely technically correct since it's
still a refspec we're taking, we just force it to be without a colon.
On the other hand, this error message will hopefully make much more
sense to people who don't know all the background, and it's not too
horribly wrong either.
