Remove the .key from the beginning of the line in rst file

The handling of . (dot) characted at the beginning of the line has
changed between the sphinx-doc versions, and it was constantly giving us
trouble when generating man pages when using different sphinx-doc.  This
commit just changes the source rst file, so there's no more . (dot) the
beginning of the line.
