As far as I can tell all four commands now behave consistently. I haven't checked whether or not they did before.
The -r switch for these commands only removes entries that are specific to the current (active) network. To remove all entries you should use -rw, e.g: /aop -rw. This is also consistent with the way entries are added (for the current network only, unless the -w switch is specified).
Perhaps these command's outputs should be supplemented with the name of the network for clarity.
