From the feedback gathered it seems like the idea of this series is worth pursuing -- thanks Peff and Junio for the reviews! In the initial RFC, we continued using `--no-warn-embedded-repo` to allow the user to add an embedded repo, but the naming of that option was not ideal. This reroll adds `--allow-embedded-repo` and deprecates `--no-warn-embedded-repo`. While I initially claimed that there were incorrectly setup .gitmodules tests with duplicate paths, it turns out that was caused by patch 4/6 of this series. I added a new patch (see 5/6) that fixes the issue. Subsequently, this means that the memory leak does not occur any more (maybe I should still include that patch -- it's an edge case that comes from a manually misconfigured .gitmodules). Lastly I cleaned up the advice message and some of the tests -- replacing `git add` with `git submodule add` only in submodule specific cases and some style cleanups. Calvin Wan (1): tests: remove duplicate .gitmodules path Josh Steadmon (5): t4041, t4060: modernize test style tests: Use `git submodule add` instead of `git add` tests: use `git submodule add` and
