[boost] Ok to commit?

Sort of administrative question :) I'm going to commit an improved version of dynamic_bitset, in the next days. The version, which is in the sandbox, has finally had Jeremy's approval. My question is: to implement find_first and find_next, two new functions I have added, I use a simple lowest_bit<T> template, which in turn requires integer_log2<T>; so there are two new header files: a) http://tinyurl.com/36zsj b) http://tinyurl.com/2lb26 I think they provide two useful facilities in themselves. Would it be ok to commit them in the boost/ folder? Or should they belong to boost/detail/? Or maybe boost/pending/? -- Genny.
