input: reset the counters when a three-digit sequence is not completed

When <Esc><Esc> is followed by digit 0 or 1 or 2 but then NOT two more
digits follow, then both the escape counter and the digit counter should
start afresh when a new ESC code arrives.

This fixes https://savannah.gnu.org/bugs/?58788.

Bug existed since before version 2.0.6.
