`curses.wrapper` returns the return value of the function it is passed,
but its function argument is declared as `Callable[..., Any]` while its
return type is `None`. This changes the definition of `curses.wrapper`
to use a `TypeVar` that relates the return type of its function argument
to its own return type.
* adding ascii, panal and textpad modules to the curses module.
* added curses/panel.pyi and curses/textpad.pyi to test/pytype_blacklist.txt
just like curses/__init__.pyi because they all import _curses. (This
may not be the right thing to do)
* Added missing annotation for start_color() and wrapper() functions
* 1) Changed Optional types to be optional arguments (checked documentation and manual experiments to make sure I was doing it right)
2) Modified format to match CONTRIBUTING.md conventions
3) corrected a few missing return types or other mistaken type
annotations
- Updates documentation related to previously required comment headers.
- Removes all comment headers from stubs
- Occasionally included a header for stubs that were noted to be incomplete or contained todo's.
