Thanks.

Actually, we haven't done an implementation for Emacs yet, and I don't 
think we are saying that we did in any place. If we had done an 
implementation already, then we sure would have made it available for 
others to use.

Both approaches may be valid: Starting with a simpler problem and 
generalize, and starting with a more difficult problem and just use only 
part of the solution.

In a post from you that I was only able to read very quickly several 
days ago, there was some talk about bidi display being handled 
differently for overlays than for other parts. I have to go back to that 
thread and think through how it may or may not affect our plans, and 
I'll certainly get back to you about it.

Regards,    Martin.
