Subject: Introduce the concept of nodes that are semantically transparent:
 they are skipped when looking for previous or following high-level macros. 
 Examples include roff(7) .ft, .ll, and .ta, mdoc(7) .Sm and .Tg, and man(7)
 .DT and .PD.  Use this concept for a variety of improved decisions in various
 validators and formatters.

While here,
* remove a few const qualifiers on struct arguments that caused trouble;
* get rid of some more Yoda notation in the vicinity;
* and apply some other stylistic improvements in the vicinity.

I found this class of issues while considering .Tg patches from kn@.
