input: intercept a spurious keycode and say what the actual problem is

Xfce Terminal sets TERM to xterm-256color even though it does not have
all the capabilities that an xterm has, leading it to misinterpret some
escape sequence and produce a spurious 0x24C key code.

Intercept this mistaken key code and tell the user what is wrong.

This mitigates https://savannah.gnu.org/bugs/?64578.
