input: don't take multiple keystrokes to be a single sequence

For some reason the keyboard code seems to assume that all integers
waiting in the keybuffer form a single sequence.  But this isn't the
case: when there is an escape (0x1b) among them, then that is where
a new sequence starts.  So, prevent the input code from considering
an escape after a non-escape as part of the current sequence.

This fixes https://savannah.gnu.org/bugs/?47839.
