    LICENSES: Add paragraph about doc/groff.texi.
    
    Background for my claims regarding the intentions of the manual's
    authors:
    
    Trent Fisher's seem to be expressed in the earliest commit of what was
    then "doc/groff.texinfo".
    
    https://git.savannah.gnu.org/cgit/groff.git/commit/doc/\
    groff.texinfo?h=1.14&id=af2d6f8e589f9fc58b98fafaad36f90302ca4b62#n33
    
    Werner Lemberg expressed them directly in email to Debian groff
    maintainer Colin Watson, and by updating this very file with a notice
    that I have not altered in substance.

    LICENSES?id=8cc38f1b9268e1c9974979eb0270754ba7f33499
    
    The third and most recent author of the manual is me.  I value the
    document bearing a license that is GPL-compatible for the reason
    expressed in this file.
