Hmm, I'm not sure that that's really such a good recommendation.  Adding
this advice breaks M-: completion, for example.  I think a more refined
solution is due, if this is to be considered a supported use case...
Namely, I suggest implementing icomplete-in-buffer as a
completion-in-region-function, like some other in-buffer completion
frontends are implemented.
