asyncio.StreamReader documentation incorrectly declare its initialization argument "limit" to be "None" by default https://docs.python.org/3/library/asyncio-stream.html#asyncio.StreamReader

In the source code it is set to _DEFAULT_LIMIT https://github.com/python/cpython/blob/0afada163c7ef25c3a9d46ed445481fb69f2ecaf/Lib/asyncio/streams.py#L353 

_DEFAULT_LIMIT is set to "2 ** 16 # 64 KiB" https://github.com/python/cpython/blob/0afada163c7ef25c3a9d46ed445481fb69f2ecaf/Lib/asyncio/streams.py#L19

This information is especially needed when you get the exception "asyncio.streams.LimitOverrunError: Separator is not found, and chunk exceed the limit" and want to increase the limit, but you don't have the initial value and you have to look at the source code to get it.

PS: this is my first ticket, I don't know if I should have open one for such a minor detail in the documentation
