commit 81a5e17861aa5654d0802241acc0a84a357c9f75
Author: G. Branden Robinson <address@hidden>

    man pages: Standardize GNU GPLv3 comment headers.
    
        * contrib/gdiffmk/gdiffmk.1.man:
        * contrib/mom/groff_mom.7.man:
        * tmac/groff_www.7.man:
          + More closely follow the model language in the GPLv3 text,
            and make the legal terms comments consistent with each
            other.
          + Identify groff as "the GNU roff type-setting system", for
            consistency with about 50 other in-tree man pages, HTML
            documents, macro package implementations, and one ms
            document.
    
        * contrib/gdiffmk/gdiffmk.1.man:
          + Identify page as Free Software.
          + Genericize self-references after the first; that is,
            "gdiffmk" and/or "it" becomes "this program".  (The
            proposition that roff documents are programs is easily
            defensible, particularly in the instant case of
            groff_mom(7), which already bears all the constructs you
            need to demonstrate Turing equivalence; it writes to a
            "tape" by defining macros and strings, and conditionally
            branches along its length with the .if and .while requests.)
    
        * contrib/mom/groff_mom.7.man:
          + Add warranty disclaimer paragraph from GPLv3 model.
