tkinter.ttk.Scale().configure([name]) now returns a configuration tuple for name
or a list thereof for all options. Based on patch Giovanni Lombardo.

funtion -> function; configuraton -> configuration; defintitions -> definitions;
focusses -> focuses; necesarily -> necessarily; follwing -> following;
Excape -> Escape,

* "Return true/false" is replaced with "Return ``True``/``False``"
  if the function actually returns a bool.
* Fixed formatting of some True and False literals (now in monospace).
* Replaced "True/False" with "true/false" if it can be not only bool.
* Replaced some 1/0 with True/False if it corresponds the code.
* "Returns <bool>" is replaced with "Return <bool>".

On Windows use UTF-16 (or UTF-32 for 32-bit Tcl_UniChar) with the
"surrogatepass" error handler for converting to/from Tcl Unicode objects.

On Linux use UTF-8 with the "surrogateescape" error handler for converting
to/from Tcl String objects.

Converting strings from Tcl to Python and back now never fails
(except MemoryError).

* Use the 'p' format unit instead of manually called PyObject_IsTrue().
* Pass boolean value instead 0/1 integers to functions that needs boolean.
* Convert some arguments to boolean only once.

They now return NotImplemented for unsupported type of the other operand.

Add __all__ to tkinter.__init__ and submodules.  Replace 'import *'
with explicit imports in some submodules.
