I have a small repository with some large externals. When the externals fail to 
update or checkout completely, the action continues with the next external or 
the main repo and then returns a 0 error code. I expected and should have 
received an error. This breaks our automated builds. My work around will be to 
--ignore-externals and then add a separate checkout/update for each external.

Please Cc me since I'm not on this list.

Thanks,
Harvey
