Re: [vim/vim] long lines automatically become foldable even with set nowrap (Issue #21000)

> This behaviour is controlled by the 'foldminlines' option. I can see that it might be unintuitive for non-wrapped lines however.

'foldminlines' also changes how other folds behave. E.g. you have a foldexpr control the folding behavior, and then non-wrapped long lines become foldable regardless of foldexpr results. Setting 'foldminlines' affects both the foldexpr-specified folds and non-wrapped-long-line folds.

And, there is no single value to set 'foldminlines' to that can achieve desired behavior. When resizing the window, the same line may wrap to 3, 4, or more screen lines depending on the window width, and 'foldminlines' will consult the number of wrapped lines, even if we set nowrap.
