[New-bugs-announce] [issue37014] fileinput module should document that openhook and mode are ignored when reading from stdin

[Grant Wu]

New submission from Grant Wu <grant.wu at petuum.com>:

https://github.com/python/cpython/blob/master/Lib/fileinput.py#L326 shows that the openhook and mode are ignored when reading from stdin.

Since part of fileinput's functionality is to abstract over whether one is reading from stdin or over a file, I think this abstraction leak should be documented.  One common use case where this might break is when attempting to set the file encoding using the included fileinput.hook_encoded functionality.
