Herewith I commit the results of a several hour romp through the
pmax section 4 documentation, inspired by PR#4527. Lots of typos, misspellings, and grammatical errors corrected. A foolish consistency (the hobgoblin of my small mind) in capitalization enforced for certain trademarks (DECthis, DECthat, and so on). A little white space added here and there for clarity. Some nroff peccadillos tended to. Further remarks over issues not dealt with will be committed in the PR.
