Subject: [PATCH] Make maxclassrepeat=1 behavior consistent with docs

When setting maxclassrepeat=1, the rule would be inactive and allow passwords containing 2 consecutive characters from the same class. Only when setting maxclassrepeat>=2, the rule would behave as expected.

This issue was already addressed in pam_cracklib many years ago: https://github.com/linux-pam/linux-pam/pull/9
