Actually, we have been building screen with 16 color support. With the
attached patch and the addition of ...
term xterm-256color
... to ~/.screenrc, emacs 'M-x list-colors-display' shows 256 colors and
emacs-zenburn-theme is pleasant to look at :-)
If emacs handled the "screen.xterm-256color" term type emitted by screen
when --enable-colors256 is set, then the 'term xterm-256color' would not
be required. This should be fixed upstream, but meanwhile, 'term
xterm-256color' is a fully functional workaround AFAIKT.
