* ext/tk/*: Support new features of Tcl/Tk8.6b1 and minor bug fixes.
( [KNOWN BUG] Ruby/Tk on Ruby 1.9 will not work on Cygwin. )
* ext/tk/*: Unify sources between Ruby 1.8 & 1.9.
Improve default_widget_set handling.
* ext/tk/*: Multi-TkInterpreter (multi-tk.rb) works on Ruby 1.8 & 1.9.
( [KNOWN BUG] On Ruby 1.8, join to a long term Thread on Tk
callbacks may freeze. On Ruby 1.9, cannot create a second
master interpreter (creating slaves are OK); supported master
interpreter is the default master interpreter only. )
* ext/tk/lib/tkextlib/*: Update supported versions of Tk extensions.

The normal Motif editing characters are supported, along with many Emacs bindings. For example, Backspace and Control-h delete the character to the left of the insertion cursor and Delete and Control-d delete the chararacter to the right of the insertion cursor. For entries that are too large to fit in the window all at once, you can scan through the entries with the scrollbars, or by dragging with mouse button2 pressed."
