Is this a tiny bug?

The tip is automatically extracted from the first line of the function's
docstring (tuple.__doc__).  The docstring was in error, and I happened to
fix it a few weeks ago (so you won't see this in 2.2a4).  It looks like the
docstring for tuple() was a cut-and-paste job from the docstring for list(),
and whoever did that forgot to s/list/tuple/g.
