Right. Actually, if you implemented the \setenv idea, you could set the
environment variable LINES to get that effect. Except that you will
then also have to implement the part that looks at the LINES variable,
but we have code elsewhere that looks at COLUMNS, so that would only be
consistent. Again, see comment above that the lines and columns
checking might be a bit inconsistent at the moment.
