Unary minus can be reformatted into a comment

[NathanSnail]

Repeated use of unary minus on a long line can cause code to be reformatted into a comment. Short lines are handled correctly and formatted into -(-x).

To reproduce:
Create the following program:

_ = (- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 5)

Observe that stylua -c suggests

1        |-_ = (- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 5)
    1    |+_ = ----------------------------------------5

which is incorrect.
