commit 50a9092bfa82900b0c07556f5b203a1a9c05d59c
Author: G. Branden Robinson <address@hidden>
Date:   Tue Nov 6 12:11:23 2018 -0500

    Include space in diagnostic message corner cases.
    
        * src/libs/libgroff/error.cpp * (do_error_with_file_and_line):
        If:
          a program name is known;
        but
          no file is being processed or the line number is negative,
        then there was no space between the program name (with colon),
        and the succeeding diagnostic message.
    
        Example: lookbib:fatal error: no databases
    
        Fixes <https://savannah.gnu.org/bugs/index.php?54971>.
