No, they are not. At least, they are not under XEmacs 20.4, 21.1 and
21.2 and, unless I am very much mistakes, Emacs in any of it's recent
incarnations.

Heck, I believe that TRAMP (a remote file access mechanism) runs under
Emacs 19 and I /know/ that it fails to do the right thing without
handlers being invoked for `file-name-as-directory'.
