I mean that `s.find_begin("ii");`, `s.find_begin("ii", 5);` and
`s.find_begin("ii", s.begin()+5);` should all be valid (and the latter 2
should mean the same thing) - not overloading the existing `s.find()`.

This would allow using iterators returned from s.find_begin() in subsequent
calls to find_begin.
