[groff] 70/105: [eqn]: Recast generated diagnostics.

[G. Branden Robinson]

gbranden pushed a commit to branch branden-2023-05-22
in repository groff.

commit 9a2ed504b446fc6ca1ba92471f6a184ba9467723
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Fri Apr 7 19:30:43 2023 -0500

    [eqn]: Recast generated diagnostics.
    
    * src/preproc/eqn/main.cpp (main): Prefix generated *roff diagnostics
      with name of input file (the document).  Use `tmc`/`tm1` to coalesce
      multi-line diagnostic onto one line of output to stderr.  Tighten
      wording.  Continues the long process of fixing Savannah #52463.
    
    Also reflow long source lines.
