OTOH, for example
(put-text-property (point) (1+ (point) 'font-lock-face '(:family "Arial"))
doesn't have that effect (when point is at one of the 's'-es) - the
bug's still there.
A couple of more experiments:
- Buffer text 'asdasdasdasdsssssssss' - the problem occurs only on at
the first 3 's'-es.
- Buffer text 'asdasdasdasdaaaaaaaaa' - the problem occurs at positions
2, 5, 8, 11 and [14..] - that is, the first 3 's'-es, and then for all
'a'-s at the end except the first one (that comes after the last 'd').
