Hmm indeed, it doesn't seem to happen with emacs -Q.  Sorry, I didn't
expect that, it was late when I wrote that message.

I spent several hours to debug this issue with my setup.  It behaves
like a Heisenbug.  I cannot reliably reproduce, so I can't just bisect
my setup.  And whenever I thought I have a way to debug...it's gone.
Debugging is hard anyway, since AFAICT redisplay plays a certain role.

I only know that when reverting your patch, the problem is gone as well
(I guess quantum Emacs counts this as a debugging attempt).

I've no idea how to make progress, so feel free to ignore, since the
issue is not hard to avoid for me by rebinding RET in dired.

Michael.
