} Subject says it all. The empty string $'' is not passed to commands the same
} way the empty strings "" and '' are:

$'...' is not a quoted expression, it's a substitution (at least as far
as zsh is concerned).  It behaves like expanding a $parameter reference,
except that the value is the string inside the '...' part.

Thus
    set -- $''
is more akin to
    x=''
    set -- $x
than to
    set -- ''

This does appear to be out of step with other shells.  Follow-ups to
zsh-workers.
