Fixing this might get ugly because the inline eqn(7) handling in
roff.c is a hack, because you don't want

  preceding text
  .EQ
  a = b
  .EN
  following text

to render as

  preceding texta = bfollowing text

and because handling of source code spacing in -Thtml is tricky.

The impact of the issue is relatively small, just some bogus
horizontal spacing.

So i have added it to the TODO list.

Similarly for opprime, which is potentially hard to implement
and does not seem very pressing.

But thanks for reporting!
