This consolidates the handling of my_fgets return values, so that interrupts are always handled, even if they come after EOF.

[bpo-32528]()/GH-13528 changed `asyncio.CancelledError` such that it no longer inherits from `concurrent.futures.CancelledError`. As this affects existing code, specifically when catching the latter instead of the former in exception handling, it should be documented in the "What's new in 3.8?" document.
