Just guessing, but suppose that a .qmail file consists of
one or more blank lines only. Since it is not empty, the
default delivery instruction does not apply. And it does not
contain any instruction for qmail-local to follow.
By requiring that the first line of a .qmail file is not
blank, qmail-local can always identify a set of delivery
instructions.
