in repository groff.

commit 819645e8b25d91700fb5d01f8583749e5f9f4e0c

    [grops]: Document -p, --version in usage message.
    
    * src/devices/grops/ps.cpp (usage): Document -p and --version options.
    
    Also organize usage message consistently with our others, and stop
    wrapping the output line: we know neither the width of the terminal nor
    the length of the `program_name` string we're interpolating.  See commit
    b4de44f0, 19 July.
