Good, thanks for having a look, submitted to groff.

Yes, i'm aware of these two differences, but followed the
concept of "one change at a time".

I agree that the mandoc behaviour is useful and the groff behaviour
is useless, confusing, and likely unintentional.  I'll probably
look whether groff can be improved.  I can't believe anybody relies
on the current behaviour.

Yes, doc.tmac-u hardcodes a limit for inserting a virtual .D1 macro
of >= 26\(en for nroff, but 38 for troff.  That is weird, but the
end-result usually looks OK, ...

 ... so probably mandoc should follow.
