The line used to be as wide as the screen, but I changed it so that the
last column would not be used, thinking this may have been an issue.  It
seemed to alleviate some of the problem, but it's not entirely gone.

FWIW, I set term to vt100 before I go into screen.

Curses module to access the library, but it's readily recognisable what I'm
