revison: Fix strangeness detection

The regexp breaks with patch series having more that 9 patches, because
'*' was a greedy qualifier, eating up every but the last digit of the
patch number. I have forgot to commit the extra '?' which makes it
non-greedy, making the whole thing behave as expected.
