Looks like Colloquy was never made to handle reverse.
Tested against other clients. Bersirc (an open source IRC client) sees Reverse and Italics just fine. Hydra IRC sees them both and transmits back just fine. X-Chat sees reverse but not Italics.
Anyway, yeah, it has to be Colloquy's issue, not mIRC.
Edit: I did post to Colloquy but they're claiming mIRC's not conforming to IRC standards when it comes to this, even though most other clients I've found have handled it the same way... Oh well. I did my job. :< (Oh, and pIRCH98 does the same as Colloquy, but it's obsolete, so.)
