Hello all,

I don't think so, -d "" is just a list with an empty string.
So -d '\0' is equivalent to -d '', '\0' is here to let the user express
an empty string in a list, which wouldn't be possible otherwise (like
how would one specify empty string in a list like 'ab<empty-string>cd').

Not sure what you mean there, -d"" is the concatenation of -d and '',
which is standard.
Did you quote the correct guideline? “Guideline 7: Option-arguments
should not be optional.” here there's an option-argument, that's an
empty string.
