This gets more nasty. When using 'git add .' you secretly add the submodule to the index. But it is neither shown in status nor diff --cached. commit actually complains there is nothing to add. But then once you add a local file to the index you can commit and secretly take the submodule change with you. What I think needs fixing here first is that the ignore setting should not apply to any diffs between HEAD and index. IMO, it should only apply to the diff between worktree and index. When we have that the user does not see the submodule changed when normally working. But after doing git add . the change to the submodule should be shown in status and diff regardless of the configuration. I will have a look at that. After that we can discuss whether add should add submodules that are tracked but not shown. How about commit -a ? Should it also ignore the change? I am undecided here. There does not seem to be any good decision. From the users point of view we should probably not add it since its not visible in status. What do others think?
