doc: clean up manpages

Many of the manpages didn't treat literal text as literal text.  I've
tried to normalize some of the restructured text to make it a bit more
regular.

several of the synopsis lines are still untouched by this cleanup, but
i'm not sure what the right way to represent those is in .rst,
actually.

In particular find that if i rebuild the manpages, sometimes i end up
with some of the synopsis lines showing – (U+2013 EN DASH) where they
should have -- (2 × U+002D HYPHEN-MINUS) in the generated nroff
output, though i have not tracked down the source of this error yet.
