bug in "file.readlines()" function. It doesn't detect end of the line when line is ending only with 0x0D byte. In python3.1 it works fine (as I expect). File in attachment should has 6 lines not only 1 as python2.7 returns.

Either use mode 'U' or the io module if you want to match 3.x.

>>> open('testFile').readlines()
['# blaaaaa\r#\r\t# blaaaaaaaa\r\t#\r\t#\r#blaaa\t\r']
>>> open('testFile', 'U').readlines()
['# blaaaaa\n', '#\n', '\t# blaaaaaaaa\n', '\t#\n', '\t#\n', '#blaaa\t\n']
>>> import io
[u'# blaaaaa\n', u'#\n', u'\t# blaaaaaaaa\n', u'\t#\n', u'\t#\n', u'#blaaa\t\n']
