This is really great, thank you. Even a partial implementation of this
command is a huge improvement.

The implementation makes me a little nervous; particularly here:

    # rm -rf patches.N
    shutil.rmtree(newpath)
    # go to the previous patch level
    if curpatch:
        ui.write(_("\nPushing to %s patch:\n") % (curpatch))
        ret = q.push(repo, curpatch, None, None, None)
    # cancel any rollback as it does not make sense for a complex command
    q.removeundo(repo)

If something were to go wrong with the merge this has the potential for
losing work. In my local copy I'm going to do something like:

    ui.write(_("\nBackup queue saved to %s\n") % newpath)

instead. Backup behaviour should perhaps be a configuration option?
