non-descriptive messages on Options menu

[Bauke Jan Douma]

I have a fairly standard emacs setup here.
Version 22.1.

When I select Options -> Customize Emacs -> Settings Matching Regexp,
then enter some setting that is not found like foobar, the message is:
No customizable items matching foobar.

When I select Options -> Customize Emacs -> Options Matching Regexp,
then enter some option that is not found like foobar, the message is:
No customizable items matching foobar.

It would be nice if these messages, and mutatis mutandis the ones for
Faces and Groups, read:
No customizable settings matching foobar, and
No customizable options matching foobar
...

I tend to forget which menu-item I just chose, and the message thus
would inform me.

Thank you.
