Wow, thanks for the amazingly fast reponses everyone!
I did wonder about the space there, but because it was generated by
fig2dev (fig→pic), I assumed that it would be correct, but it's
actually fig2dev being buggy here:
diff -urN transfig-3.2.5.c.original/fig2dev/dev/genpic.c

It's also losing numerical precision with %.2f format strings which
clip off the extra precision and result in really awful alignment.
Fixing these issues results in a perfect figure, so this is not a
groff issue in any way.
Many thanks again!
