+Subject: [PATCH] Fix invalid incremental decoding check.
+
+The first condition is only necessary if we have not read enough
+(enough being defined by src_last, not src_end which is the end
+of the image).
+The second condition now fits the comment below: "if not
+incremental, and we are past the end of buffer".
