after the command is executing is bogus because it may still be needed if the same command is going to be executed again (for example if you "bind-key a bind-key b ..."). Making a copy is hard, so instead add a reference count to the cmd_list. While here, also print bind-key -n and the rest of the flags properly. Fixes problem reported by mcbride@.
