Just for the records: I guess there might be similar problems in
other usage cases, too.  However, using Emacs 24.3.91 I did not
encounter so far a 2nd scenario where a temporary buffer like
*Completions* gets displayed in a ridiculously small window.
We need two temp buffers like *Marked files* (small) and
*Completions* (bigger) for this bug to show up.
