Yes, this was my general conclusion (i.e., I didn't actually do it!) For 
freshly written code, I could not think of a case where I would suggest 
a null deleter but that doesn't mean that there isn't one.

I think before adding a null deleter to Boost, it might be useful to 
think about the cases in which it is necessary and whether they occur 
enough to encourage its use. After all, if it is in Boost, chances are 
that it is a proper way to do things.
