shelve: allow --patch and --stat without --list for a single shelf
It's annoying having to specify --list and --patch/--stat when all you
really want to do is to dump a patch. This creates an explicit
--patch/--stat command that is executed if --list is not specified. It
ensures that 1) there is only one shelf name specified and 2) that the
shelf exists. Then it redirects to the original listcmd code.
