Filter channel mode changes associated with join/parts

[maertsen]

I'm using smartfilter in combination with irssi-xmpp. It helps me get rid of join/part spam, but I'm left with user specific channelmodes that are set upon join.

E.g. 13:35 -!- mode/conf@conference.example.org [+p user] by conf@conference.example.org

Is ignoring channelmodes that are related to join/parts something that you would be interested in? I would imagine this to be useful for irc in general (e.g. 13:36 -!- #chan [+o foo] by bar), not just for my xmpp use-case, though the applicable modes are likely to differ.
