This is what I was thinking of, and the effect should be subtle.  The
light blue underline is pretty good; it would be nice if it could be a
choice between a few similarly well-chosen defaults (I'm hardly the one
to provide them, though).  

I would make this an Emacs first-class option rather than an optional
library.  I think it's really useful.
