Most options were formatted like this in the manpage:
-o ARGUMENT
--option ARGUMENT
but a few were formatted like this:
-o ARGUMENT | --option ARGUMENT
or even as:
-o, --option ARGUMENT
The former seems least confusing to me, so switch all of the documentation
to this format.

In nroff manpages, a blank line adds vertical white space. When this is
followed by another command that also starts a new paragraph, the result
is a vertical skip twice as big as the normal inter-paragraph gap. The
solution is to use a line that contains just "." for white space within
the manpage, instead of a blank line. The resulting manpages look better.
