A %s or %[ field was treated as overflowed whenever the next input
character could continue it, even when the field width from the format
ended the read. sscanf_s("abcdef", "%3s", buf, 10) returned 0 with an
empty buffer instead of 1 with "abc". Run the overflow check only when
the buffer capacity reduced the width.
The DQbtGaBKlaw import was a throwing stub (libcCyberUnknown17). It is
the NID of "strnlen_s", which C11 K.3.7.4.4 defines as strnlen that
returns 0 for a null pointer.
The removed stub comment from #358 described its call site as
float -> float, which contradicts the hash-verified name; #492 left the
stub untouched for that reason.
