Treat __init__.pyc same as __init__.py in module_list

There are some circumstances where packages on disk could only have a .pyc
version of __init__.py. It would be nice if ipython would autocomplete them as
well. I've been using this in a production environment for several weeks now.

IPython/core/completerlib.py

@@ -91,6 +91,7 b' def module_list(path):'
     # Now find actual path matches for packages or modules
     folder_list = [p for p in folder_list
                    if isfile(pjoin(path, p,'__init__.py'))
+                   or isfile(pjoin(path, p, '__init__.pyc'))
                    or is_importable_file(p) ]
 
     return [basename(p).split('.')[0] for p in folder_list]
