[Idle-dev] VIDLE for Python 3

[Bruce Sherwood]

I should add that there is in VIDLE one additional file,
FileRevert.py, implemented by Guilherme Polo, I believe. Since it is a
new file, it doesn't show up in the diff file.

In help.txt is this new comment:

Revert  -- Discard all changes since the last save
