commit fa4c27e933f303ef774963352c2e8854e951b9f1
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Tue Sep 7 06:23:34 2021 +1000

    [troff]: Update exit status literals.
    
    * src/roff/troff/div.cpp (top_level_diversion::begin_page):
    * src/roff/troff/input.cpp (exit_troff, abort_request, do_error,
      fatal_with_file_and_line): Use standard C library preprocessor symbols
      `EXIT_SUCCESS` and `EXIT_FAILURE` instead of 0 and 1 literals,
      respectively.
