[issue21140] Idle: saving Shell or an OutputWindow should default to .txt

[Terry J. Reedy]

Terry J. Reedy added the comment:

In #11830 I suggested that Shell should be added to this issue. #26327 does the same, as the prompt and output are not code.

At least in 3.x, these mixed code and text files should be encoded utf-8 (which is the same as ascii for all ascii files), as code files are (at least by default).  The encoding search and determination in IDBinding.py is a bit baroque.  The local encoding should not ever be used for 3.x code.

If we do something with #11838 (save runnable code from Shell), the default should then revert to .py.  I don't want a patch here to make this excessively difficult.
