I changed this for bash-4.3/readline-6.3. The meta key is only active for
the duration of a single call to readline().
Readline assumes in many places that the caller checks whether or not it's
being called with a terminal or equivalent as stdin/stdout, but I can look
at adding a check for a terminal here.
