Support for re-running scripts on only failed repos

[klauern]

Describe the solution you'd like
I was using git-xargs for a set of small changes on a number of repositories, but discovered a few of them have different behavior than anticipated, and I wanted to re-run a modified script against only those failed runs. Is that possible?

Describe alternatives you've considered
Manually editing a repos.txt file with the repos and re-running seems to be the answer, but it's clunky (imo).
