Wow, cool, thank you very much! That works exactly as I need it, great.
BTW, before you push out another release, could you before have a look
at the proof-of-concept patch regarding "rich text" support for the
textview that I sent to the list in August, and tell me whether the rich
text support looks OK to you from the syntactical point of view? If yes,
then I'd like to improve the patch to make it work properly with escaped
characters and multi-column Unicode characters.
