Thanks, the bug is in good hands.

There may be another bug in replace-match. But it was something I saw
nearly half a year ago. I was in a hurry and chose a quick workaround to
move on.

The bug is this: replace-match may move point to point-min when changed
region doesn't involve point-min. The trigger is similar to this bug
i.e. smie-config-guess in first-change-hook. Unfortunately I forgot how
to reproduce this bug. I thought I mention it in case it is obvious from
the code.

My workaround is to wrap replace-match in save-excursion. I'll remove
the save-excursion and see if it comes up again.

Leo
