Upstream talking here...

Why do you want this?
What is so special about empty input compared to other non-manual-page input
that you want special handling for one but not for the other?

For example, doas it matter for you what

  echo foo | mandoc

does, and if it matters, why does that matter for you?

While mandoc(1) usually strives for groff compatibility *inside manual pages*,
handling arbitrary low-level roff(7) input *outside manual pages* is not among
the goals of mandoc(1).

I'm not saying what you are asking for is unreasonable.  What i'm trying to say
is that i need to understand what you need this for before i can make up my
mind whether and how your goals might be reached.  Bapt@'s very ad-hoc patch
does not strike me as particularly useful as far as i can see so far.
