Maybe C2HS generated functions should not use "param omitting" style.

I am making a code generator that reads source and generating some wrappers. It worked fine with my own source. But failed with C2HS result since C2HS generated source uses param omitting.

For example, when I defined a `Rect` type with pointer hook, I would get a `withRect` function as `withRect (Rect fptr) = C2HSImp.withForeignPtr fptr` which omits the last param.

Since `withRect` is generated and not supposed to be read by human, I wonder why it was like this. Analyzing code and refill the parts seems really complex to me....
