Perhaps elm should respect the environment variables LINES and COLUMNS,
even on termcap systems.  Although these variables are technically defined
only for terminfo, the idea seems to be very useful to me, and the
implementation is simplicity itself:

	co = tgetnum ("co");
	if (getenv ("COLUMNS") != NULL)
	    co = atoi (getenv ("COLUMNS"));

and similarly for LINES.  The code above is just a sample taken from what
I am going to do for ispell;  it can be improved if the double call to
getenv offends you.
