True.

I don't know the reason why the user who reported this problem did it, 
but they *did* find a need to set ido-max-window-height to 1, apparently 
(which has the same effect).

TBH, of course, I'm more worried about the "future bug" regarding 
icomplete-vertical-mode. But maybe we'll switch to child frames 
exclusively for this purpose by them.

None from me. If that's the simplest fix we can do for the release, 
please go ahead.
