All of strto{d,l,ul} have the same statement:

	If the subject sequence is empty, or does not have the expected
	form, no conversion is performed; the value of nptr [the char *
	parameter] is stored in the object pointed to by endptr [the
	char ** parameter], provided that endptr is not a null pointer.

Thus, if any of these functions are passed the string " x", the character
pointed to by the end pointer should be the space.
