in repository groff.

commit d12fc1837d63fd6859c940fccd50abaad7a48d55
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sun Aug 28 16:29:41 2022 -0500

    [eqn]: Drop support for undocumented '-D' option.
    
    It has been undocumented, and issued a warning of its obsolescence upon
    use, for 30 years, since groff 1.06 (September 1992).  That's plenty
    long enough for a deprecation cycle.
    
    * src/preproc/eqn/main.cpp (main): Do it.
    * NEWS: Add item.
