This is pretty much what I was planning to do but I missed something
rather obvious:

I need to conform to screen's "STRING ESCAPES" syntax for coloring and
therefore I can't just use the underlying xterm's ctlseq's as I was
naively trying to do.  :-(

Or to put it another way, since screen's syntax only supports 8+8 colors
via the "color" letters [k, r, g, y, .. etc.] plus the "bold" attribute
for brighter versions.. it looks like I would need to add 256-color
support to screen's hardstatus line first and then use th "extended
syntax" in my scripts.

Sounds like a lot of work for something the vast majority of screen
users would consider totally silly, with the caveat that whatever I came
up with would likely never make it into mainstream screen and I would
have to maintain my patch separately.

I guess I'll use your solution above for now and tweak the 16-color
color palette in my X resource file to something a bit more civilized
than the xterm defaults.

Thanks, much appreciated!
