Hey, thanks for the excellent port. After years of use I finally ran into a bug today.
If I do a multi-line paste with cmd-v, it doesn't post in the window until after I've typed a new line. This often results is multiple pastes as I hit cmd-v several times trying to get it to complete, followed by embarrasement when I see I've pasted the same snippet 5 times. Horribly irc-rude.
