IllogicTC means that * in place of ? will also catch channel notices, those sent using /notice #chan, rather than just private notices sent using /notice yournick.

if you do plan to lump channel notices together with private ones, it would be wise to include some indication of that within the line being added to the window otherwise the user, when he returns, might be given the false impression that a notice sent to the channel was sent to them personally. that, and avoid responding to those notices.
