Will that require renaming to `submodule-lib.c`? No, that is different from what I wrote above. Just like there is the middle-layer diff-lib.c between the top-layer builtin/diff.c and the low-level helper sets in diff.c, I envision that between the top-layer builtin/submodule.c and the low-level helper sets in submodule.c, there would be the middle layer submodule-lib.c. If a single cmd_submodule_set_url() function implements the whole of "git submoduel set-url" (by calling helper routines in submodule.c and those currently in builtin/submodule--helper.c), I would expect it to reside in builtin/submodule.c.
