you see, it just matched 3 characters, but...
here you are tricked by the semantics of a quantified grouping operator.
A quantified group only remembers the last match, and as your group only
matches a single character, 'c' it is:)

so you have to refer to the whole match (rx.group(0)) or get the
quantification inside a group. e.g.
>>> rx = regex.compile('\(\(.\|\n|)+\)')
