Remove a global rule or user rule. The provided index is the same that's printed when you run 'rules ls'. Note that after each removal/addition, the index of the commands change. So be careful when removing them after each other.
You can also specify an optional parameter (index_end) so you can remove all commands from 'index' to 'index_end', including 'index_end'.
