roff(7): Fix content and style nits.
* Document the Autologic APS-5 as an early replacement for the Graphic
Systems (by then Wang) C/A/T. The 1981 copy of CSTR #54 that was
included in "Unix 4.0" (a transitional release between Unix System III
and System V that seems largely not to have escaped AT&T) documents
only the APS-5 as an available target for device-independent troff.
The colophon of the HRW reprints of the Seventh Edition Unix manuals
also identifies the APS-5 as used in their production.
* Fix incorrect terminology.
* Pull parenthetical into its own sentence.
