[issue13229] Improve tools for iterating over filesystem directories

[Nick Coghlan]

With the release of 0.3, I'm pretty happy with the WalkDir design (previous versions coerced the output values to ordinary 3-tuples, now it will pass along whatever the underlying iterable produces with changing the type at all).
