Oops. I obviously never tested the Windows build, and that curly brace
is obviously extraneous.

It came from first looking at the other cases (that free the
allocation inside the normal "if (wpath) {" thing, but then deciding
that "Hey, there's nothing wrong with calling 'free()' on a NULL
pointer", simplifying the code, but leaving the (now extraneous) curly
brace.

Dirk, please just take that obvious fix. I'm sure you'll see it in
your windows cross-build..
