Indeed, that works, as does

Info node `(elisp)Basic Completion'

(without the space after the right paren)

Patch for this and one other instance of the same issue attached. I've
also attached a proposed patch for hiding the 'Info node' and 'URL'
prefixes in *Help* buffers, since I find they just get in the way.

First one could go to either emacs-26 or master. Second one I think is
master-only (does it require a NEWS entry?).
