This is a regression from _groff_ 1.22.4, introduced in _groff_ 1.23.0.

When you format 2 _mdoc_ pages back to back, `Nm` calls in the second
interpolate the name of the first.

But only with _groff_ 1.23.0, and only with some output drivers, not including
"utf8".

...unless you specify `-rcR=0`, disabling continuous rendering.

So this is another page trap/end macro sort of problem.
