• Spyder Version: It happens in spyder3 and 4, with the difference that indent guides isn't present in spyder3

I'm not sure what is the best way to fix this, after #5130 and #5122 it will be four different checkable options, implementing each one independently will cause some duplicated code.

We could iterate over all options when building the menu. Just a thought :-)
