Find should not allow things like '-!'.

- it's ugly to read or write first of all,
- it's redundant to the regular '!', ',' '(' and ')' punctuation operators,
- it's not mandated by any specification,
- it's not supported by any other reference implementations,
- it's inadvertently happening by some blurry corners of the code,
- it's not documented.
- it's not tested.

yes, and more: it's an implementation bug I would say.
That just slipped through.

Things like this bug are impossible to see by just reading the code.
Eventually a fuzzing tool may find that unintended behavior.
We should clear that code area and simplify it.
Readability helps for better maintainability.
