Having done some minor changes to git-submodule.sh recently, I wondered if we weren't at the point where it would be a nice approach to invert the C/sh helper relationship. I.e. write git-submodule.c, which would be the small entry point, it would then mostly dispatch to a submodule--helper, which would in turn mostly dispatch to a new submodule--helper-sh (containing most of the current git-submodule.sh code), which in turn would re-dispatch to the C submodule--helper (which as an aside, then sometimes calls itself via process invocation). It's quite a bit of spaghetti code, but means that there's a straighter path to porting some of the setup code such as the "--check-writeable", is_absolute_path() etc. being changed at the start of the change here to git-submodule.sh.
