Only after the user fixes the problematic submodule and runs "git submodule update" again, the second error is found. And the user needs to repeat until all the problems are found and fixed one by one. This is tedious. Instead, the command can remember which submodules it had trouble with, continue updating the ones it can, and report which ones had errors at the end. The user can run "git submodule update", find all the ones that need minor fixing (e.g. working tree was dirty) to fix them in a single pass. Then another "git submodule update" can be run to update all. Note that the problematic submodules are skipped only when they are to be integrated with a safer value of submodule.<name>.update option, namely "checkout". Fixing a failure in a submodule that uses "rebase" or "merge" may need an involved conflict resolution by the user, and leaving too many submodules in states that need resolution would not reduce the mental burden on the user.
