fix "#pragma option" crash when character count is over 31

For some reason `i` will be `32` after our for loop so an OOB happens when code tries to assign `'\0'` to `name[32]` since `name` size is 32.
Doing a `-1` to `i` fixed this issue and now throws `error 038: extra characters on line` when character count is over 31.
