I'll take a look through that series. Interesting. If I build git from master after reverting 55568086, I do indeed observe the issue it claims to fix (unable to add ignored submodules). However, if I build from 9ef23f91fc (the immediate parent of 55568086), I do not see the issue. Investigating this further, it seems that 55568086 addresses an issue that does not appear until later on in the series in ff6f1f564c (submodule-config: lazy-load a repository's .gitmodules file). Perhaps this was a result of reordering commits during a rebase. In other words, I get correct behavior until 55568086, and in 55568086..ff6f1f564c^ if I revert 55568086. Looking at ff6f1f564c, I don't really see anything that might be related to git-add, git-reset, or git-diff, so I'm guessing that this only worked before because the submodule config wasn't getting loaded during `git add` or `git reset`. Now that the config is loaded automatically, submodule.<name>.ignore started taking effect where it shouldn't. Unfortunately, this doesn't really get me much closer to finding a fix.
