The root problem seems to be that troff is sort of wishy-washy about
the distinction between underlining and italics, regarding one as a
fallback for the other rather than the two as distinct operations.
http://savannah.gnu.org/bugs/?57462 seeks to address this, though no
one has yet volunteered to work on it (understandable, as it seems a
fairly significant change requiring a broad knowledge of the groff
code base).
