[Openmcl-devel] Aha!

[Ron Garret]

I think I've had a breakthrough!  It turns out that if you use my red- 
green cursor blink hack and move the cursor around with the mouse or  
the arrow keys then it DOES leave red and green squares behind.  It is  
only when you actually type a close-paren that they get reset to  
white, and then only in the same line as the cursor is currently on.

So I suspect that Hemlock is repainting the entire current line every  
time you type a close-paren and hence undermining the matching-paren  
highlighting.

Anyone know offhand where the code that does that repainting might be?
