I can propose something simple on Monday: remove from GUI (like we do in
Linux) and always act as if the pref is off.
Here is what I had in mind. I discovered that the checkbox was not
hidden but disabled on Linux. I added code to hide it and ignore it.
This seems simple enough, but of course should be checked by Mac/Win people.
I also removed traces of it in the English User's Guide, and added some
entries in release notes. Feel free to improve on the wording.
PS: I do not think it is worth applying this to master. We will either
end up fixing the feature or removing it altogether.
