[Doc-SIG] Does the "is" operator only matter for mutable object?

[INADA Naoki]

In
http://docs.python.org/py3k/tutorial/datastructures.html#comparing-sequences-and-other-types
,

The operators is and is notcompare whether two objects are really the same
> object;
> this only matters for mutable objects like lists.


I think this notation may confuse readers of the tutorial. For example, pep8
recommands
using is operator for immutable singleton objects like None.

Shall we remove letter part?
