Subject: split_stream: guard against body being NULL.
X-Git-Tag: v1.2~3
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=00c699ae751519a0fc8f25fb99cb0554e5b3f617;p=wiggle.git

split_stream: guard against body being NULL.

If body is NULL, adding 'len' to it makes no sense.
Just abort early in that case.
