xchat-2.0.4 binds ctrl-w to "kill tab" instead of "kill word" ala emacs keybindings. kind of annoying, as I'm used to using ctrl-w when typing text. It may also be inconsistent with behavior set by readline(3), so users need to learn yet another set of keybindings. let's kill this behavior before it becomes expected.

I think this issue is already sorted out: http://xchat.org/faq/#q215
