The difference seems to be that the Bell Labs [nt]roff program has a
built in nroff back-end IIRC, i.e. it doesn't output ditroff
intermediate format, where as we use the gorgeously named grotty.  So
Bell Labs [nt]roff has more `if (TROFF) ... if (NROFF)' code in it.

Not just on output either, if NROFF is true then .ps is ignored,
checking for ligatures is skipped, etc.
