I'm not sure I understand the UI and the interaction.  When there are
several hits, they usually are spelled (almost) the same.  So how
would the user pick up what he/she wants using the completion UI?

And where are the candidates shown -- in the minibuffer? or in a
special buffer, like Xref does?
