[docs] [issue35533] argparse standard error usage for exit / error

[Philip Rowlands]

New submission from Philip Rowlands <pythonbugs at dimebar.com>:

Because error() mentions standard error and exit() does not, I assumed exit() did not use stderr, but it does.

Please mention standard error in the description of exit().

Relevant code at:
https://github.com/python/cpython/blob/3.7/Lib/argparse.py#L2482
