But if this goes into dwim_ref, then won't it be usable for refspecs? Or
even if it isn't, then imagine the user who doesn't know this and types

  git push :foo

unwittingly deleting the remote "foo".

Yes, that is unlikely (since why would they push the tracking branch of
foo?), but I don't think it makes sense to argue that it doesn't have
confusing (and potentially dangerous) consequenses.

I think that is quite clever and doesn't have any meaning for a revision
specifier already. I like it.
