Fancy mode becomes really slow when folds

[Thanatermesis]

I have a lot of foldings to organize better my code, but SmoothCursor becomes really slow when moving normally on these files, I assume it is because is counting "real lines" instead of "visual /showing lines"

Thank you for submitting the issue! This is a known issue. However, there are some difficulties in fixing this. (PR is welcome!) Fortunately, there is a workaround for this (not elegant though). Try #62!
