Now, support longnam-keys (e.g. '%CTT' on tkdnd-2.0; however, still
not support tkdnd-2.0 on tkextlib), and symbols of parameters (e.g.
:widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on;
those are attributes of event object). It means that Ruby/Tk accepts
not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but
also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }".
It is potentially incompatible, when user passes symbols to the
arguments of the callback block (the block receives the symbols as
strings). I think that is very rare case (probably, used by Ruby/Tk
experts only). When causes such trouble, please give strings instead
of such symbol parameters (e.g. call Symbol#to_s method).
