[tor-commits] [tor/master] Use parsing code for the simpler controller commands.
commit 01b07c548b93bcc58adac612a02c69dcb4b63b28
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date: Tue Apr 2 19:00:23 2019 -0400
Use parsing code for the simpler controller commands.
(This should be all of the command that work nicely with positional
arguments only.)
Some of these commands should probably treat extra arguments as
incorrect, but for now I'm trying to be careful not to break
any existing users.
