By saying broken, do you mean that this regex
   r'Searching for OPUSH on([^\.\n\r]+)|Channel:([^\r\n]*)'
follows the pathological case of exponential complexity ? From what
I have learned such complexities occur due to nested repetitions, and the
one mentioned above does not seem to have that complexity. Does it ?
