Andy, thanks.  Yes, you're right.  When I run screen as you suggest,
several color artifacts disappear.  In particular I get 16 system colors
instead of just 8.

Instead of specifying -T screen-256color every time, one can just put
'term screen-256color' into .screenrc.  I'll update the docs to show this
when I make the release current.

Andrew.
