Improve the ANSI sequence parsing/stripping/pass-through in spy()
Strip all *but* the expected keyboard input sequences (arrow keys, pgup/dn, home, end, insert). Pass-through a bare ESC key (albeit with delay). ESC immediately followed by a key other than '[' should be very quickly passed through.
Increase the max ANSI sequence length from 31 to 256 chars.
