but just some text embedded in the docs.

Also remove paragraph about implicit relative imports from tutorial.

    Optional keyword parameters *linejunk* and *charjunk* are for filter functions
    (or ``None``):
 
-   *linejunk*: A function that accepts a single string argument, and returns true

-   Python 2.3.  Before then, the default was the module-level function
-   :func:`IS_LINE_JUNK`, which filters out lines without visible characters, except
-   for at most one pound character (``'#'``). As of Python 2.3, the underlying
-   :class:`SequenceMatcher` class does a dynamic analysis of which lines are so
-   frequent as to constitute noise, and this usually works better than the pre-2.3
-   default.
