It seems you just explained the difference yourself---unless you have redefined NULL according to your own liking. If you define "a NULL string" as the same as "an empty string", then of course there is no difference---by definition! If you don't, though, I think the difference is obvious.

Anyway, we already had that discussion in another branch, didn't we? Why restart it here?
