For all practical purposes they should be equivalent in D code. I 
suppose the distinction exists because somebody claimed he can 
make sense of it. Some API may rely on distinction between null 
and empty string, like XML DOM, though I don't think such 
interface is very useful.

Also for some reason boolean value of a string is derived from 
ptr instead of length... meh.
