[New-bugs-announce] [issue5048] Extending itertools.combinations

New submission from Konrad <konryd at gmail.com>:

The function itertools.combinations might benefit from making
the 'r' (length of the combinations) argument optionally a sequence.

With that change one could call combinations(sequence, [2, 3]) in
order to get all combinations of length 2 and 3.
In particular, one could call combinations(sequence,
range(len(sequence)) in order to get *all* combinations of given
sequence.

The change would be backwards compatible as it would check for
sequential arguments.
