Yes, this is truth. However amd64 asm code already reads more pointers from stack (when number of them is smaller then number of arguments needed to pass via registers when doing function call), so I think that this function can be documented that returns "minimal number of arguments". So it is really an issue? Or should be function extended to skip all characters between [ and ]?
For the sake of simplicity, I think it should be acceptable to return an upper limit, so I suggest we rename these functions to `__ms_scanf_max_arg_count_internal` etc. This also eliminates the need to check for `%*`; we only need to count `%` characters and assume there can be no more arguments than them.
