The latter.   I was clumsily trying to say "your changeset description
isn't clear enough".   If you had said "shlwapi: fix thinko in sizeof(array)"
I might have woken up out of my stupor enough to understand the change.

BTW the way you define the new size, as a magic constant, seems
bad.  Can you use 4 * sizeof(WCHAR), or whatever, instead of 8?
And even then, the '4' seems almost as bad.
