On the flipside, memchrW() doesn't stop at a NUL...

Ops! Please ignore this patch, the bounds of the memchr are way off...
Curiously, this did not crash on any of the tests I run even though it
is always going past the string boundary. On the other hand, using
strchrW would reliably crash after roughly 10 minutes of activity...
