When using `show-paren-mode', I've noticed a slight problem: suppose you
have show-paren-mode turned on, and point is at -!- in the following:
(setq a -!-(car b))
Then the opening and closing parens of `(car b)' are both highlighted.
Now type a few characters quickly. If you are quick enough, the
characters you type are also highlighted, because the overlay which
highlights the `(' has not yet had a chance to be moved. The tiny patch
below (against CVS HEAD, rev 1.69) makes the two relevant overlays
front-advancing, which seems to fix the problem.
