Suppose I have a bunch of folds for more than one line each. How to make shuffle them as folds not lines?
In case of lines it can be done by external
shuf or any other command (see https://stackoverflow.com/a/17643450/359866 for example).
So the question is for more general case of multiline folds.
fold1 subfold text1 fold2 subfold text2 fold3 subfold text3
fold1... fold2... fold3...
After shuffle for example
fold2 subfold text2 fold1 subfold text1 fold3 subfold text3
