[groff] 02/07: [grohtml]: Use warning() upon usage errors.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit 5ceb0eee6676ebed0836f884ba5e3769c24b80d9
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sat May 22 18:14:51 2021 +1000

    [grohtml]: Use warning() upon usage errors.
    
    * src/preproc/html/pre-html.cpp (scanArguments):
    * src/devices/grohtml/post-html.cpp (main): Use libgroff's warning()
      instead of printf() to emit diagnostic about unrecognized paramter to
      `-x` option.  This sends the diagnostic to the standard error stream
      and continues the long process of fixing Savannah #52463.

        * tmac/groff_www.7.man: Stop using the "www" macro package.  The
        macros it exposes are not part of the quasi-standardized man(7)
        language, and thus should not be used in man(7) documents.  See
