Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Fri Oct 16 22:41:38 2020 +1100

    Update editor aids.
    
    src/preproc/eqn/main.cpp:
    src/preproc/pic/main.cpp:
    src/preproc/tbl/main.cpp:
    src/roff/troff/input.cpp: Update editor aids.
    
    Assist Vim as well as Emacs, and set fill-column/textwidth to 72, like
    other groff source files.  Use Vim settings that work well with GNU
    indentation style.
    
    Drop short-form Emacs Local Variable setting.
    
    src/roff/troff/input.cpp: Wrap a clump of overlong source lines.
