[ After seeing the following issue all day, I can't reproduce it. I'll
try and find a way to reproduce the problem reliably. But perhaps it
will ring bells for someone who has more knowledge of screen and/or
rxvt-unicode. ]
I have a permanent caption set in ~/.screenrc which occupies the last
line of the console. Because of that I would expect that starting
screen in a console of, say, 80 lines would present a value of 79 to
programs running within a screen. However, LINES (in bash) remains at
80, and the following Python code would report the same thing:
>>> from fcntl import ioctl
>>> from struct import unpack
>>> from termios import TIOCGWINSZ
>>> lines, cols = unpack('HH', ioctl(1, TIOCGWINSZ, " " * 4))
>>> print lines
80
Perhaps that's part of the problem? But take that with a big pile of
salt; I'm not very familiar with the internals of screen or TTY
programming. Just a guess.
