[issue45296] IDLE: Change Ctrl-Z note in exit/quit repr on Windows

[Terry J. Reedy]

New submission from Terry J. Reedy <tjreedy at udel.edu>:

On Windows:
>>> exit
'Use exit() or Ctrl-Z plus Return to exit'
>>> quit
'Use quit() or Ctrl-Z plus Return to exit'
>>> exit.eof
'Ctrl-Z plus Return'

On *nix, 'Ctrl-Z plus Return' is 'Ctrl-D (i.e, EOF)'
IDLE uses the latter even on Windows, and Ctrl-Z does not work.

Both exit and quit are instances of _sitebuiltins.Quitter
https://github.com/python/cpython/blob/e14d5ae5447ae28fc4828a9cee8e9007f9c30700/Lib/_sitebuiltins.py#L13-L26
class Quitter(object):
    def __init__(self, name, eof):
        self.name = name
        self.eof = eof
    def __repr__(self):
        return 'Use %s() or %s to exit' % (self.name, self.eof)
    def __call__ [not relevant here]

We just need to replace current exit/quit.eof as indicated above on startup.
