If client does LIST "" * it sees:

..
* LIST (\Noselect) "#shared"
* LIST (\Noselect) "#shared/user"
* LIST () "#shared/user/box"
..

If you had namespaces with prefixes "#shared/" and "foobar/", doing a
LIST "" * would still show both namespaces' mailboxes. Of course LIST ""
foobar/* wouldn't show #shared/*.

Crossing namespace boundaries means a single LIST command listing
mailboxes from more than one namespace.
