feedback: make an "Unbound key" message disappear on the next keystroke

When nano reports "Unbound key" or "Unknown sequence", this message
should stay onscreen only for the relevant keystroke, not for any
succeeding keystroke.

This addresses https://savannah.gnu.org/bugs/?59119.

Bug existed since before version 2.0.6.
