Re: *real* number of lines a window can display currently

calc.el could use such a function.  If you want more justification for
this statement I'd have to refresh my memory about the details of how
its stack is displayed & I'd probably refer you to some old posts on
the subject (in comp.emacs).  To get the stack to display correctly in
different situations, I've just empirically altered one of its
functions so that it works.  My situations are Windows 2000 Pro at
work, XEmacs 21.4.8, Windows 98 at home, XEmacs 21.4.8, a Sun platform
at work--accessed via Telnet in console mode & with Xemacs 20.4
(earlier with Emacs 19.34), and Mandrake Linux 9.0 at home, with a
forgotten version of XEmacs and both in console mode and with
X-windows.
