OK, a new version of exu, that recognizes the size of the
text window, is now available as pre-alpha-4:

For instance, ed will automatically give you more lines and 
more columns, if available.

It looks for LINES and COLUMNS first, then tries ioctl(),
then defaults to 24x80 if all else fails. On the two systems
I tried, it picked up the size correctly.

I think that eliminates the last deficiency of the new exu
(doesn't use ncurses) versus 2.5 (needs ncurses).
