Re: Test to determine character left-overhangs a tab stretch.

[Keith David Bershatsky]

Thank you very much for solving the mystery as to the segfault -- greatly 
appreciated!!!

I agree that merely skipping over that section of code in this situation is not 
a good idea.  Now that a reliable test exists, I can begin working on devising 
a method to redraw the fake cursors along the tab stretch after it gets drawn 
anew.
