These seem like reasonable requests, although I'd have to check the
std::back_inserter to be 100% sure.
I'll probably target them for Boost.Filesystem Version 3.
Note however that path has some but not all of the characteristics of
a standard container. I'd want to see persuasive use cases for adding
functionality - just making path more like a std container without
good reason is likely to lead to interface bloat without offsetting

A use case would make this more compelling.
