git-push: do not error out on empty revision set

Browse source 
"-r REVISIONS" here specifies the search space of the branches to push, and
warned if no branches are found in that space. I don't think an empty set
should be an error, but a warning for consistency. The warning message will be
improved by the subsequent patches.
