prompt: allow rebinding also ^N, ^Q, and ^Y at the yes-no prompt

Checking for the literal ^N, ^Q, and ^Y before checking for do_toggle
and full_refresh made it impossible to rebind any of those keystrokes
to these two functions.  (Not that anyone would want this, but...)

Problem existed since version 4.3, commits 341601e1 and 82aea04c.
