[issue2705] incompatible change to warnings.showwarning

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Well, all you have to do is to change the hook's signature to the new
one and, since the last parameter is optional, it should not cause any
backwards compatibility problems. That is, the new hook should work fine
on Python < 2.6 as well. Am I missing something?
