Thanks.

This should mention *LENGTH, not LENGTH.
I think this comment (and the similar comment in language.h) would be
clearer if it mentioned that LENGTH is both an in- and out-parameter.

I noticed recently that this entire comment is shifted over by a space.
Could you move it back?

The code bits are approved with those two changes.
It still needs a doc review.
