Thanks.

This round is marked as the sixth, but I still see quite a many
style issues, which I expect not to see from long timers without

Overlong line that does not have to be.

			if ((where == WHERE_AFTER
                             ? in_tok->next : in_tok->previous) == arg_tok)

Needless brace pair.

Ditto.
