Allowing the source bytes to be longer than expected.
This makes a huge difference for extraction speed.
10s versus 45s. Versus 17s for the original groupcompress code.
Also, the compiled version in _groupcompress_c seems ~ the same speed as
the patch-delta.c version.
At the very least, the extra memory copy overhead negates any benefit.
