#9 End key doesn't work

[Malenko Dmitry]

When I pess the <End> key cursor goes to the end of _text_
and select some area after the actual end of text.

I do not consider going to the end of the _text_ a bug. This is the
intended behaviour. For going to the end of the _line_, use C-e.
The tktext widget uses emacs key bindings. It this should be changed,
it should be in the text widget, not in the editor.

As for selecting at the end...this is also the behaviour in tktext. Maybe
we should fix it, but then it should be in the text widget again.
