handler_normalize returns a new handler which is a newly allocated 
string. Therefore, checking for errors is reasonable. Maybe we should 
change the signature, tough. If it wrote the new handler to a pointer we 
give it to, for example, we could reserve the return value for NULL for 
success and error_no for failure.
