[boost] [disjoint_sets] 1.49.0 docs out-of-date? pending?

I noticed that

http://www.boost.org/doc/libs/1_49_0/libs/disjoint_sets/disjoint_sets.html

references

boost/disjoint_sets.hpp

but, AFAICS, no such file exists; however, clicking on the file nonetheless
redirects to

boost/pending/disjoint_sets.hpp

which presumably is the intended reference. So, aside from what looks like
a slight error in the present disjoint_sets docs, what is the purpose of
this pending directory? I had never noticed it before and I don't remember
stumbling upon a reference to it until now. Looks like it contains a
hodgepodge of miscellaneous headers...

Thanks,

- Jeff
