5/16    In emacs 19.34.6 for NT, if I bring up a .BAT file containing this
        line:
                if exist foo goto bar
        I get an error "No match 2 in highlight (2 bat-keyword-face)".  But
        if I change the line to "if exist foo echo bar" or "if not exist foo
        goto bar" the error doesn't occur.  Any idea?  Thx.  -- yuen
