Right, it's actually worse than that: the entire folding is
redone at every key press. :) If you feel particularly adventurous
and you aren't easily upset by tiny details like segfaults, you might
try the patch below. It's a naive attempt to alleviate the problem
for autocomplete. It's definitely not the right fix. But I don't
understand the code well enough to come up with a better one, so I'll
leave finding the real solution to the grown-ups.
