Looks to me like a fault in comparison format. Normally, you'd expect
that 4.10 follows 4.9 - that is, that the version number is a tuple of
integers - but this is attempting a naive string comparison on it.
Check for an ipython bug tracker and report the matter; that ought to
be fixed.
Bear in mind that your change now means that you're accepting too much
- for instance. '4.6' is not less than '4.10', even though it's
supposed to be rejecting that. Presumably this won't be a problem on
your own system, but for upstream, a more reliable fix will be needed.
