    gropdf(1): Clarify.
    
    * Fix unfinished list of common pagination schemes.  Motivate the
      letter-prefix scheme.
    * Clarify where the 'pagenumbering' device control command needs to be
      placed relative to a *roff page break.
    
    Exhibit:
    
    $ groff -ms -Tpdf <<EOF
    .pdfpagenumbering roman
    .P1
    .LP
    Foobar.
    .\"pdfpagenumbering Decimal \" WRONG
    .bp
    .pdfpagenumbering Decimal \" RIGHT
    This is the second page.
    EOF
