[Groff] pdfmark Documentation Update

[Keith Marshall]

Hi Werner,

Attached is an interim patch to further extend the PDF format documentation 
for pdfmark.tmac

    Interim documentation update.

    * pdfmark.ms: (GROFF-WEBSITE): new string; use it in references and
      examples.
      (Section 2.5): add definitions of D and Z operators, for use with
      pdfhref macro.
      (Section 2.5.4): complete description of pdfhref macro usage for
      "Linking to Internet Resources"; provide examples.

Best regards,
Keith.
