Partial fix

Never mind, don't test that patch, it doesn't help.  There appear to be several
bugs:

1. VarBstrCmp was passing -1 to CompareStringW, meaning it expected the BSTRs
to be NULL-terminated.	This is wrong, and the previous patch addressed that.
2. VarBstrCat was assuming its arguments were NULL-terminated.	This is also
wrong, and this patch addresses that.
3. CompareStringW only compares until a NULL.  This needs a test case to show
the correct behavior.
