Patch by Sjoerd Mullender for better compatibility with the version

from Python 1.5.1:

If after __init__ finishes no new elements variable was created, this
patch will search the instance's namespace for all attributes whose
name start with start_ or end_ and put their value in a new elements
instance variable.
