I'm not sure there was intended to be an implication that "whence"
would pay attention to noaliases.  If used inside an "autoload -U"
function, for example, it's also going to report the "wrong" thing for
any command names used in that function, regardless of the global
setopt.

If we apply this change, I wonder if we should also extend the -a
option to continue to list aliases despite its current description of
"throughout the command path".  It already lists builtins as well as
$path locations.
