[New-bugs-announce] [issue22865] Allow pty.spawn to ignore data to copy

[Geoff Shannon]

New submission from Geoff Shannon:

While using the pty.py module I had cause to want to be able to silently eat characters from the input stream.  I discovered that because of the check for end of file being "if not data" that there was no way to do this.

Since the default function used by spawn and _copy is a thin wrapper on os.read, I figured that it would be useful to interpret None as a sentinel value meaning "this is not EOF, but there's nothing I actually want to copy over."
