"git clone --resurse-submodules --reference $path $URL" is a way to reduce network transfer cost by borrowing objects in an existing $path repository when cloning the superproject from $URL; it learned to also peek into $path for presense of corresponding repositories of submodules and borrow objects from there when able. * sb/submodule-clone-rr: clone: recursive and reference option triggers submodule alternates clone: implement optional references clone: clarify option_reference as required clone: factor out checking for an alternate path submodule--helper update-clone: allow multiple references submodule--helper module-clone: allow multiple references t7408: merge short tests, factor out testing method t7408: modernize style
