[Python-ideas] chdir context manager

[Steve Dower]

FWIW, when Windows revised their API set, GetCurrentDirectory and SetCurrentDirectory were completely removed. This seems a pretty strong move away from these APIs. (This only applies to new-style Windows 8 apps; desktop apps can still call them, but the intent is clear.)

Cheers,
Steve
