Documentation formatting and cleanup

Following what appears to be the predominant style, format
names of commands and commandlines both as `teletype text`.

While we're at it, add articles ("a" and "the") in some
places, italicize the name of the command in the manual page
synopsis line, and add a comma or two where it seems appropriate.
