Are you interested in implementing something?  You could re-open this
bug then, no problem.  Or are you maybe just evaluating if you'd like to
do it?  Please give a hint.

The places you mention sound right.  It's probably all in term.c.  But
I'd like to add, that in principle all places writing to the terminal
have to be checked at least.

And corner cases have to be taken into consideration :-).  Pulling
something out of thin air: What happens if we write RGRG to the
bottom-right corner, where R is one red char, and G is 1 green char,
say.

And maybe we have to check for characters that are more than 1 column
wide?  I don't remember something like that from when I last worked in
this area, but I'd check what the situation is nowadays.

That's all I can say without studying the code more in detail, which I'm
trying to avoid :-).
