Subject: [PATCH] More suscinct and flexible escape char fix

To handle the possibility of the escape character being anywhere in the
key passed to `key_binding_not_set`, I've opted to use parameter
replacement to escape every escape character. This is more suscinct, and
will make sure every '\' is handled.
