[PATCH 7/7] man/tabs.1: Revise "Margins" subsection.

[G. Branden Robinson]

* Consistently set name of program in bold, not roman.
* Favor man(7) font macros over *roff font selection escape sequences,
  except for man page cross (and self-) references.
* Favor English phrases over Latin abbreviations.
* Recast for (attempted) clarity.
