Well, it's possible to look at the slant of the font, but that's not
always reliable.
By the way, \emph doesn't correspond to /I, because "/I" will never
be iteratively applied. It's only in the setup that this slightly non-
intuitive behaviour occurs.

Wah?!? I could see that being useful in the future.
Hmm, if that's the case I've never seen it -- /B seems to me to
always snap to the most bold font available. But maybe my testing
hasn't been wide enough.
