This is interesting, since the size of the window (as shown when I
turn on line numbers ('-N') in 'less') is actually *25* lines high
(columns are correct at 80).
After resizing the rxvt window to increase the number of lines by 1,
'stty -a' correctly shows that there are 26 rows. Weird!
Thanks for any ideas,
