[racket-dev] code coverage coloring

Okay, not sure how that help, but my messages have probably been too opaque.

I just chatted with Eli on the phone about this and I see two things
that DrRacket could provide

a) DrRacket could defer to the the language-info stuff for the default
settings in the language dialog instead of using the same defaults for
every language. That seems pretty straightforward (modulo some
possibly tricky UI questions wrt to what happens when you actually set
things in the dialog and are editing the #lang line and go back and
forth).

b) We could invent some kind of API whereby a langauge cna offer
information about programs that run (or that don't run) and DrRacket
could watch for that information and display it. Some kind of API that
would subsume the things that errortrace, the syntax coloring, and
other tools currently provide.

The latter seems more ambitious but perhaps also more useful as it
might be useable by, say, Guillaume with his ideas for colored error
messages.
