Not that I know.  In any case, this seems like it's an Emacs bug, and
shouldn't we fix that?

If I say "xterm -geometry 800x20", then it seems to be constrained to
the screen size.

Well, this isn't about fixing my frames -- I can do that with a couple
of lines of Emacs Lisp.  But Emacs seems to be buggy here, and it would
be nice to fix that bug.

Nope.
