Sorry for the confusion. Of course this doesn't happen with emacs -Q, only
when running it with my .emacs. I just thought it might be helpful.

Ah. Well today starting from emacs -Q I can't reproduce it. However, if I
load my .emacs I still can't reproduce it in that same emacs. One difference
that I notice today is that after running the progn I can read the top line
namely "208. ..." instead of only the continuation of that line. I swear it
worked yesterday, that is that I saw the bug in emacs -Q.
In case you are interested in what happens in my contaminated emacs, if I run
C-x = after (forward-sexp) then it says a left parenthesis, but if I use
`(progn (forward-sexp)(what-cursor-position))` then it says the next character
is C-j. Furthermore, changing it to (prog2 (forward-sexp)
(what-cursor-position) (redisplay)) causes it to work properly (i.e. no bug).
I guess I'm probably on my own on this one, since even I can't reproduce it
reliably in emacs -Q, so what functions that I should start debugging?
Thanks,
Ivan
