transient--show-hint: Renamed function

Finally make the switch from flip-flopping between using either "OLD:
Rename function" or "NEW: Rename function" to "NEW: Renamed function".
Note that I am still consistently using present tense — "renamed" is
an adjective.  (Though maybe the phase I am entering now is one during
which I rotate through *three* possible approaches.)  oO
