    To let cases like "ESC U" through, we could only filter out escape 
    sequences whose length is more than 2.  Function keys are almost always 
    longer that 2 characters, I think.

Emacs does not translate ESC U to Meta-U through function-key-map.
ESC is an ordinary prefix key in that context.  So I would expect that
sequences such as ESC U won't be picked up by this code anyway.

    I agree that having that display is a valuable debugging option.  Perhaps 
    we could have that with some modification of "C-h c", like when it's 
    invoked with an arg.

Since other people found it useful, I agree with that.
