Properly escape dashes on the man-page

Properly escape dashes on the man-page

On UTF-8 systems groff interprets unescaped dashes as hyphens and
escaped dashes as minus signs. Unescaped dashes can cause problems
when searching for or copying and pasting options. This patch ensures
that dashes in command-line options are escaped and that everything
else is left unescaped.
