- + I think the attribute-interleaved text might be possible to do
- cunningly, as well: we autodetect a basically VT-style
- terminal, and add 256-colour sequences on the end. So, for
- instance, we might set ANSI-yellow foreground, set ANSI-red
- background, _then_ set both foreground and background to the
- appropriate xterm 256-colour, and then display some
- appropriate character which would have given the right blend
- of the ANSI-16 fore and background colours. Then the same
- display code should gracefully degrade in the face of a
- terminal which doesn't support xterm-256.
- * current best plan is to simulate the xterm-256 shading from
- 0/5 to 5/5 by doing space, colon and hash in colour A on
- colour B background, then hash, colon and space in B on A
- background.
