Mailman 3 [issue22785] range docstring is less useful than in python 2 - docs

2 Nov 2014

      New submission from Ned Batchelder:

The Python 3.4 docstring for range is:
{{{
 |  range(stop) -> range object
 |  range(start, stop[, step]) -> range object
 |
 |  Return a virtual sequence of numbers from start to stop by step.
}}}

In Python 2.7, it said:
{{{
    range(stop) -> list of integers
    range(start, stop[, step]) -> list of integers

    Return a list containing an arithmetic progression of integers.
    range(i, j) returns [i, i+1, i+2, ..., j-1]; start (!) defaults to 0.
    When step is given, it specifies the increment (or decrement).
    For example, range(4) returns [0, 1, 2, 3].  The end point is omitted!
    These are exactly the valid indices for a list of 4 elements.
}}}

Note that Python 3 seems to imply that the end-point is included, while Python 2 made clear that it was not.  "Arithmetic progression" is a bit involved, but it would be good to mention that the end-point is omitted in the Python 3 docstring.
