672237dc6c warnings.catch_warnings() now returns a list or None instead of the custom 
WarningsRecorder object. This makes the API simpler to use as no special object
must be learned.

Closes issue 3781.

d08a8ebf2a Closing issue1761. 
Surprising behaviour of the "$" regexp: it matches the
end of the string, AND just before the newline at the end
of the string::

    re.sub('$', '#', 'foo\n') == 'foo#\n#'

Python is consistent with Perl and the pcre library, so
we just document it.
Guido prefers "\Z" to match only the end of the string.

1ff91d95a2 Patch # 1140 (my code, approved by Effbot). 
Make sure the type of the return value of re.sub(x, y, z) is the type
of y+x (i.e. unicode if either is unicode, str if they are both str)
even if there are no substitutions or if x==z (which triggered various
special cases in join_list()).

Could be backported to 2.5; no need to port to 3.0.

2ee4128e9b Remove test.test_support.guard_warnings_filter. 
test.test_support.catch_warning is more full-featured and provides the same
functionality.

Since guard_warnings_filter was added in 2.6 there is no
backwards-compatibility issues.

21d3a32b99 Combine the functionality of test_support.run_unittest() 
and test_support.run_classtests() into run_unittest()
and use it wherever possible.

Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.

From SF patch #662807.

3646ab98af Fix for part of the problem mentioned in #725149 by Greg Chapman. 
This problem is related to a wrong behavior from mark_save/restore(),
which don't restore the mark_stack_base before restoring the marks.
Greg's suggestion was to change the asserts, which happen to be
the only recursive ops that can continue the loop, but the problem would
happen to any operation with the same behavior. So, rather than
hardcoding this into asserts, I have changed mark_save/restore() to
always restore the stackbase before restoring the marks.

Both solutions should fix these two cases, presented by Greg:

>>> re.match('(a)(?:(?=(b)*)c)*', 'abb').groups()
('b', None)
>>> re.match('(a)((?!(b)*))*', 'abb').groups()
('b', None, None)

The rest of the bug and patch in #725149 must be discussed further.

c34f2555bd Applied patch #725106, by Greg Chapman, fixing capturing groups 
within repeats of alternatives. The only change to the original
patch was to convert the tests to the new test_re.py file.

This patch fixes cases like:

>>> re.match('((a)|b)*', 'abc').groups()
('b', '')

Which is wrong (it's impossible to match the empty string),
and incompatible with other regex systems, like the following
examples show:

% perl -e '"abc" =~ /^((a)|b)*/; print "$1 $2\n";'
b a

% echo "abc" | sed -r -e "s/^((a)|b)*/\1 \2|/"
b a|c
