direct is the intended replacement, while it is not a good idea 
to pass NULL (that's why it is not documented), it may work. A 
better idea is to pass a buffer, note that neither the old API 
nor direct guarantee that no buffering is taking place, but 
for typical use cases, direct is sufficient.

If you are a user (and not a distributor), you should always 
use current git head.
