From 223798c50efcabab4ffa17e4060a8d89c929f982 Mon Sep 17 00:00:00 2001

Subject: * ext/tk/lib/tk/canvastag.rb: TkcGroup.new cannot include given
 items.   TkcGroup#exclude calls wrong method.   Add alias TkcGroup#add
 [ruby-talk:146049]. * ext/tk/lib/tk/canvas.rb: TkCanvas#dtag and some
 subcommands of   TkCanvas#addtag fail to treat a TkcTag argument. *
 ext/tk/lib/tk/event.rb: add TkEvent::Event#generate to help to send   current
 event to other widgets.
