Some display errors in corrected messages
the hl status of the message is not changed. For example if someone hls you and he fixes the message by removing your nick, the nick color is still the hl-color
same with the opposite case (the message is fixed to ADD your nick).
a /me message that is fixed displays None instead of the nick, or no nick at all if the correction doesn’t starts with /me
To fix that, we should send the new message through the whole process that checks for hl and /me, etc.
