[3.9] bpo-32751: Wait for task cancel in asyncio.wait_for() when timeout <= 0 (GH-21895) by miss-islington · Pull Request #21963

[3.9] bpo-32751: Wait for task cancel in asyncio.wait_for() when timeout <= 0 (GH-21895) by miss-islington · Pull Request #21963 · python/cpython

… 0 (pythonGH-21895)

When I was fixing bpo-32751 back in pythonGH-7216 I missed the case when
*timeout* is zero or negative.  This takes care of that.

Props to @aaliddell for noticing the inconsistency.
