I suspect the interpretation of -d '' to mean a NUL byte delimiter
may have been an accident originally (but that's a guess).  But it's
an incredibly useful feature, and has been used in countless real
life scripts.  At this point, while it is still undocumented, it is
nevertheless a feature whose omission would be considered a regression.

Others have correctly described the difference between -d'' and -d ''
so I won't repeat that, except to say that they are right.
