rust-pyo3: helper to build Python lists of revisions It really seems that the PyO3 bindings will perform less copying than their rust-cpython counterparts: instead of building a vector with the results (first copy) then passing a reference to `PyList::new`, (that therefore would have to copy again), we can pass an iterator of the elements, as long as they have a single type (`PyRevision`) in this case.
