Okay my bad, I see CR-LF now with Wine 1.1.20 when the file is New in Notepad. Wine Notepad will tolerate LF-only in a loaded file, and saves it LF-only if you re-save, however any (and only) new line breaks inserted are then CR-LF, which then saving produces a mix of both line break types in the file. I did not test this specific behavior in Windows Notepad.
