- remove all trailing whitespace

     * except when it is escaped with a `\' at the end of the line
- fix remaining .Nm usage as well
- this is from a patch I received from kwesterback@home.com, who has been
  working on some scripts for fixing formatting errors in mdoc'd man pages

Ok, so there could be a cost/benefit debate with this commit, but since I have
the patch we might as well commit it...
