Correction: The patch I gave in the last message produces:
parser.parse_known_args(['-ku'])

It doesn't take action on the '-k', and puts 'u' in extras, not '-u'.
This new patch gets it right:

Hmm: it's not an obvious Python bug, either: both math.exp and math.ceil are
simple wrappers around the libm functions, so there's little room for things to
go wrong between Python and the OS.

New submission from Ronald Oussoren:
assertItemsEqual was added to unittest.TestCase in Python 2.7 (according to the
documentation), but is not present in Python 3.3.
I'd expect it to be present in 3.3 as well, or for it to be mentioned in
documentation as not being present (either in the 2.7
Ezio Melotti added the comment:
I don't remember how it went exactly, but there were a few similar methods
(assertItemsEqual, assertSameElements, assertCountEqual). In 3.x we eventually
decide to remove the first 2 because it wasn't clear what they were doing, and
only assertCountEqual
Ronald Oussoren added the comment:
I do think this should be mentioned in the 2.7 docs, assertDictContainsSubset
is mentioned as deprecated since 3.2 in the 2.7 docs. The only problem with
that is that there doesn't seem to be a versionremoved directive in sphinx,
the best alternative seems
Mark Dickinson added the comment:
No problem; thanks for the update. By the way, if you do file an OS bug report
of some form, it would be great if you could add a link to this issue. That
might help anyone who encounters this in Python in the future.

Looks like we wrote a similar patch at the same time :)
We don't usually use versionchanged in the 2.x docs for things that changed in
