fragments in 2.0.5?

	Does 2.0.5 still report fragments? I'm in the process of actually 
thinking about moving to 2.0.5 from 1.8.1 and while converting scripts needed
to identify a frag output for parsing. While I can find lots in 1.8.1, when
fed to 2.0.5 it doesn't think they are frags:

	This is the 1.8.1 ra reporting isolated fragments:

	This is the same file (caught with tcpdump) on the 2.0.5 ra:

	No frags indicated. Is the frag output depreciated (i.e. I no longer
need to look for it in 2.0.x output)? It looks like the frag got reported as
a standard packet only 16 bytes long.
