man page fixes.

- Start new sentences on a new line, so that troff gets inter-sentence
  spacing correct.

- Remove unterminated quotation mark.

- Replace no-longer-defined "spice" macro with a literal string.

- Remove trailing whitespace.

- Close literal contexts instead of letting them propagate throughout an
  entire section.
