Yes, I think we want that flexibility, it certainly isn't that much
difficult to support it (a few lines of code, will try to code the %r/%R
variant tomorrow), and from time to time it can be useful.
Perhaps that %L or whatever character isn't taken for the expanded location
could be used too.

I don't see why we would need dynamic color names, as the color names are
to be overridable through GCC_COLORS, documented in invoke.text etc., the
list better be static and not too long, but we can add new color names in
the future when needed.
