Details:

The Texinfo manual and groff(7) do not agree on precisely what the three
vertical-motion escapes \r, \u, and \d do.

Texinfo (doc/groff.texi) documents them as moving up 1v, up .5v, and down .5v,
respectively.

groff(7) (man/groff.7.man) documents them as moving up 1m, up .5m, and down
.5m, respectively.

CSTR #54 (section 11.1) defined the three in m's.  I haven't verified whether
this corresponds with historical behavior.  Being vertical motions, v's make
more sense.
