Log message:
        Even when not the first option, --help can't have side effects.
        * tests/options.at (--debugfile): Detect bugs in this area.
        * tests/testsuite.at (AT_CHECK_M4): Avoid a process when ignoring
        stderr.
        * src/main.c (main): Fix it by deferring debugfile change.  Also,
        defer closing streams until after module tracing is done.
        * modules/gnu.c (debugfile): Make message consistent with command
        line.
        * doc/m4.texinfo (Invoking m4): Touch up the documentation.
        * NEWS: Document this fix.
