While I agree with the original poster that returning '.txt'
is preferable to the others in the list returned by
mimetypes.guess_all_extensions() at least 9 times out of 10,
being able to prioritize all of the types is not necessarily
the easiest thing to do for all of the possible returned lists.

Is using a custom comparison function along with the list
returned by guess_all_extensions() sufficient?
