As we all know, git provides `submodule add , init, update, sync, sumary, foreach, status`, but where is `submodule remove`?
will I not delete one of them sometime in the future? Although most people will not use submodule or one who uses it can remove submodule by hand, providing complete options may be a good idea. I am not familiar with C, but i can help test it. will anyone finish this feature? ---- Thanks and Best Regards, lingchax
