I suspect this is a redisplay problem, not an undo problem. How do
you see that point is in the wrong position? What does "C-x =" say
immediately after the undo?
Anyway, I tried to reproduce the problem, but couldn't: SWI-Prolog
7.3.x seems not to support the OS of my main development machine, and
all my attempts to simulate the situation by having a subprocess
insert a long string into a buffer failed: after undo I always see a
window with the single original line, the one that corresponds to your
line 15. As expected.
Can you try coming up with a recipe that doesn't involve SWI-Prolog?
Also, how important is it to have exactly the font you mention and
exactly that size? (I tried that font and that size, as well as a few
others, but that didn't help in my case.)
Thanks.
