Comment 4 for bug 660433

Thanks Julian,

I added a mock-environment and a test and send a merge request:
https://code.edge.launchpad.net/~mvo/launchpad/support-timeframe-fix-660433/+merge/38503

The branch tests that maintenance-check produces the expected output and prepares testing germinate
as well. However its not testing that yet. The test is shell based, I'm happy to rewrite it as a python unittest
if that is needed (and if the general direction is correct).
