What makes you think it's always ""?

I haven't actually tested your patch, but the way I read it, I get the
impression that it will break things like

    C-h i g (emacs-23/e TAB
and
    C-h i g (/usr/sh TAB

But the new one only handles those cases where the ".info" extension is
present, which is sadly not always the case (yup, the conventions about how
to name info files suck).

You forgot to double the backslash.

There's `delete-dups' for that.
But I also wonder whether we couldn't try to reduce the amount of
duplication (at least in some of the common cases) even before passing
the result through delete-dups.
IOW, I'm wondering where the duplication actually comes from.
