        gnats          : ChangeLog Makefile.in database.c internal.c 
                         mail.c misc.c 

Log message:
        * misc.c (open_mail_file): If the mail agent is NULL, just
        leave without doing anything.
        
        * mail.c (get_responsible_address): If the database hasn't been
        properly configured, just return the mail address as-is.
        
        * internal.c (unlock_gnats): Fail gracefully if gnats_adm_dir ()
        returns NULL.
        (punt): Try "mail user" if the mail agent can't be found or
        opened.  Add the hostname where the error occurred to the
        subject line.
        
        * database.c: Add lots of checks for database validity, to prevent
        coredumps.
        
        * Makefile.in (install-tools-arch-indep): Fix path of gnats.el.
        
        Try to cleanly handle the case where the global database list is
        nonexistent or totally invalid.
