We have here a problem that dates back to the vague and obscure wording
of the V7 nlist(3) manual page.  V7 really *does* want an empty string for
that initializer, because the array element is "char[8]", not "char *".
Later Unixes and non-Unixes have done things differently; some of them
may not have realized this, because the manual page is so vague.

Fortuitously, "{0}" is legal and correct under either interpretation,
and hence should be preferred.
