Is our solution just "recursed > operations always respect the parent config, deal with it"? For settings like branch.<name>.remote, I don't think anyone would disagree that the right thing to do is to use the per-repository config of the submodule. The repository object is already able to handle per-repository config, so this just involves callers being careful not to cache values locally in a way that conflates repositories. It should be pretty straightforward (for commands like "git fetch --recurse-submodules", for example). For settings like grep.patternType, on the other hand, it would be very strange for the behavior to change when grep crosses the submodule boundary. So I think using the parent project config is the right thing to do and the old behavior was simply wrong. In other words, I don't think this is so much a case of "deal with it" as "sorry we got the behavior so wrong before --- we've finally fixed it now". But this is subtle. Maybe some notes in the config documentation for relevant settings would help. That would make the intended behavior clearer and make debugging easier for users. Thanks, Jonathan
