@timkelty Thanks for the suggestion! Sorry for the delay as I am pretty busy recently.

I would start working on this feature soon after finishing tests as git-sweep is getting more complex. Before starting I would like to gather some ideas first on what qualifies to be cleaned up.

I guess for local branches we probably want to removes these:

• Local branches that is old enough (older than a certain age)
• Local branches that is tracking a remote branch, but the remote branch has been deleted (gone when you do git branch -vv)

Any other suggestion?

The latter is primarily what I'm looking for, though the first could be nice too.
I think that's it!
