wmfsm: Improve manpage.

In particular,
- Apply, with some modification, a patch by Jari Aalto
  <jari.aalto@poboxes.com> to clarify the format of the configuration file.
  See [1].
- Escape minus signs to avoid hyphen-used-as-minus-sign Lintian warning in
  the Debian package.
- Remove docbook-to-man comments to avoid manpage-has-errors-from-man
  Lintian warning in the Debian package.
- Add commas between short and long options for readability.
