[PATCH] Tell users that git protocol is not for pushing

["Nathan W. Panike" <nathan.panike@gmail.com>]

When one attempts to push to a git-protocol repository, one gets the
line:

fatal: The remote end hung up unexpectedly

This seems a bit obscure to me.  It is better to inform the user that git://
does not allow pushing.
