    src/preproc/tbl/main.cpp (main): Clarify error.
    Clarify fatal diagnostic in generated document by informing the user
    that the program is aborting, and also that it is groff extensions that
    are required rather than GNU troff per se (since Heirloom Doctools troff
    claims groff extension support via the .g register).
