attempting to call lineptr() with a y-coordinate off the bottom of the
screen and triggering the dreaded 'line==NULL' message box.
This crash can only occur if the bottommost line of the screen has the
LATTR_WRAPPED flag set, which as far as I can see you can only
contrive by constructing a LATTR_WRAPPED line further up the screen
and then moving it down using an insert-line escape sequence. That's
probably why this bug has been around forever without anyone coming
across it.
