This problem is a perennial favorite on comp.lang.python and in the 
cookbook, which I take to mean that there is no clear best solution. You 
can see some alternatives here
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/425044

and in the links at the bottom of that page.

One question is what to do with partial groups at the end; your version 
truncates the original list.
