Are you sure ? This is what I actually get with your example :

>>> expr = re.compile(r'[^)]\n',re.M)
>>> expr.sub('', '(Hello\nWorld)\n end of text')
'(HellWorld)\n end of text'


The problem I see is that you lose the character before the '\n',
so this could be better I think :

>>> expr = re.compile(r'([^)])\n',re.M)
>>> expr.sub('\g<1>', '(Hello\nWorld)\n end of text')
'(HelloWorld)\n end of text'
