Current Behavior

This doesn't seem like an issue at all. Just mentioning here for documentation purposes. The --show-failed-attempts flag has a minor conflict with the --clock flag. When the former is enabled, the clock is only shown till the first failed attempt. After that the number of failed attempts is shown instead of the clock.

Expected Behavior

Maybe mention about this in README and manpages. I don't think any code changes needs to be made. As seeing the clock doesn't really matter after trying the passwd.

Reproduction Instructions

The example script in the README can be modified to show this:

#!/bin/sh

BLANK='#00000000'
CLEAR='#ffffff22'
DEFAULT='#ff00ffcc'
TEXT='#ee00eeee'
WRONG='#880000bb'
