Hello,
The change fixed it for the minibuffer, but also disabled it when the
opening parenthesis was offscreen. I think this is because
`(pos-visible-in-window-p openparen nil t)` seems to return nil in that
case.
I got it to work by swapping
(or (< (length part) 4)
(and
(< (nth 2 part) dfh4)
(< (nth 3 part) dfh4)))
with
(and (>= (length part) 4)
(< (nth 2 part) dfh4)
(< (nth 3 part) dfh4))
, which did not re-introduce the problem in the minibuffer.
Thank you.
