The problem is in the displayed string.  Why not push "" to prospects
when most-is-exact.  I think completions are cycling but the displayed
string is not.

Is removal of leading space really necessary?  Things would be simpler
otherwise.

|     (concat determ

| 	    (mapconcat 'identity (nreverse prospects)
|                        icomplete-separator)
| 	    (and limit (concat icomplete-separator "…"))
| 	    "}")
|   (concat determ " [Matched]"))
