python regex: misbehaviour with "\r" (0x0D) as Newline characterin Unicode Mode

[Arian Sanusi]

Hi,

concerning to unicode, "\n", "\r "and "\r\n" (0x000A, 0x000D and
0x000D+0x000A) should be threatened as newline character
at least this is how i understand it:
(http://en.wikipedia.org/wiki/Newline#Unicode)

obviously, the re module does not care, and on unix, only threatens \n
as newline char:

>>a=re.compile(u"^a",re.U|re.M)
a.search(u"bc\ra")
a.search(u"bc\na")

<_sre.SRE_Match object at 0xb5908fa8>

same thing for $:

>>b = re.compile(u"c$",re.U|re.M)
b.search(u"bc\r\n")
b.search(u"abc")

<_sre.SRE_Match object at 0xb5908f70>

>>b.search(u"bc\nde")

<_sre.SRE_Match object at 0xb5908fa8>

is this a known bug in the re module? i couldn't find any issues in the
bug tracker.
Or is this just a user fault and you guys can help me?
