[docs] [issue14586] TypeError: truncate() takes no keyword arguments

@Brandl truncate() was the issue I ran into, no other reason. I have started on the rest of the IO module tho. I know the patch is not working but I ran into problems with getting cpython to change functions from positional to keyword.

@all

ps.
I am using code from within other C files and http://docs.python.org/dev/extending/extending.html#keyword-parameters-for-extension-functions to base my patch on but I still get "x()" takes no keyword arguments". What have I missed/Are the docs correct?
