That's a little useful to know: Inspecting the termcap, I didn't notice
much except that the enacs terminfo string was missing.  Reading screen's
code, I see that it has some logic for inferring things related to enacs.
(But I don't read it often, so I'm not familiar with the logic).

What I generally do to get some insight is to run 'script' around the
whole session and analyze the 'typescript' file.  That would at least
answer the question of whether screen or ssh was sending some string
that turned line-drawing off, or whether none of them turned it on
properly.  (How that will help me reproduce the problem, I'm not sure).
