ruby--ruby/ext/tcltklib/tcltklib.c
nagai b9bdee95f1 * ext/tcltklib/tcltklib.c (ip_init): set root-win title to "ruby" when 
the running script is '-e one-liner' or '-' (stdin).
* ext/tcltklib/extconf.rb: add find_library("#{lib}#{ver}",..) for stub libs
* ext/tk/lib/tk/textmark.rb: TkTextMarkCurrent and TkTextMarkAnchor
  have a wrong parent class.
* ext/tk/lib/tk/dialog.rb: rename TkDialog2 --> TkDialogObj and
  TkWarning2 --> TkWarningObj (old names are changed to alias names)
* ext/tk/lib/tk/dialog.rb: bug fix of treatment of 'prev_command'
  option and hashes for configuration
* ext/tk/lib/tk/dialog.rb: add TkDialogObj#name to return the button name
* ext/tk/lib/tk/radiobutton.rb: rename enbugged method value() ==> get_value()
  and value=(val) ==> set_value(val).
* ext/tk/lib/tk/menu.rb: add TkMenu.new_menuspec
* ext/tk/lib/tk/menu.rb: add alias (TkMenuButton = TkMenubutton,
  TkOptionMenuButton = TkOptionMenubutton)
* ext/tk/lib/tk/event.rb: new method aliases (same as option keys of
  event_generate) for Event object
* ext/tk/lib/tk/font.rb: configinfo returns proper types of values
* ext/tk/lib/tk.rb: bind methods accept subst_args + block
* ext/tk/lib/tk/canvas.rb: ditto
* ext/tk/lib/tk/canvastag.rb: ditto
* ext/tk/lib/tk/frame.rb: ditto
* ext/tk/lib/tk/text.rb: ditto
* ext/tk/lib/tk/texttag.rb: ditto
* ext/tk/lib/tk/toplevel.rb: ditto
* ext/tk/lib/tkextlib/*: ditto and bug fix
