Feature request: flag to return return a failure exit code

[nwsparks]

The feature request

flag to return return a failure exit code if any repo(s) do not succeed.

apologies if I missed that this is currently available somewhere, did not see it.

My use case

Would like to use multi-gitter with some cron jobs for package updating and would like a clean way of notifying when it fails on a repo.

Implementation

• I would like to contribute this feature if it's a suitable addition to multi-gitter
• I have no intention of adding this feature myself.
