Ah, your comment reminded me that something similar happened recently
near me:

   $ git push origin some-ref:HEAD

It caused a small disaster, although it was quickly fixed.

The backwards compatibility you mentioned, which can also be understood
as a non-limitation in this aspect, is worth maintaining.

I haven't had time to investigate why git-push doesn't warn (or stop)
the user when attempting that, but perhaps there's a small crack we
want to fix.  Or maybe it's something we actually want to allow...
