I was also unsure about this when coding the patch, but I read here  that:
"Specifies the length, in bytes, of the string pointed to by the
Buffer member, not including the terminating NULL character, if any."
So it's not a mistake to include a NULL character. I figured it's not
worth the trouble to change the last strcpy into memcpy, especially
because it could also be the case that it would introduce regressions
(in case some other code wrongly depends on that NULL).
Should I change offending strcpyW to memcpy?
