Summary: Entry widget inputs goes right-to-left 

Initial Comment:
Sometimes when you are typing into an entry widget, the
characters
will be inserted from right to left instead of from
left to right.
To see this, first create an entry widget.  For example:

       entry .e -width 30
       pack .e -padx 10 -pady 10

Now enter some text into this widget.  With the mouse,
click to
the right of the text and drag the mouse all the way to
the left past
the beginning of the widget.  All text in the widget
should become
highlighted.  Continue holding down the mouse button
and start
typing.  The first key press deletes the selected text
(which is correct)
and inserts the typed key.  The second key press is
inserted to the left
of the first character instead of to the right.

You can well argue that this is an unusual case since
not many people
begin typing with the mouse button still held down. 
But sometimes
(on the OS of the monopolist) a stray button-press
event will leak into
a widget as the widget is being created.  Thus Tk might
think the
button is being held down even when it is not.  (This
is rare, and
perhaps another bug - but it does happen.)

The fix to this problem is simply to add a call to
::tk::CancelRepeat in the <KeyPress> binding of
the entry widget.  I'll do that straight away.  The
purpose of this bug report is merely to document
what was done.
