I use vimperator, so the only program I use a lot which still doesn't recognize ctrl+w is Hexchat.

My friends have gotten used to see me part the channel and rejoin shortly after, cursing my fingers.

Hexchat closing on C-w is such a pain! It can't be scripted away either because it's hardcoded in the source. I haven't looked into this for some time but there does seem to have been some updates.

That sounds like the kind of thing that would be really easy to maintain your own fork for...

HexChat parting on Ctrl+w is probably one of the main reasons that drove me to use a TUI IRC client like weechat.
