submodule--helper: advise on fatal alternate error
When recursively cloning a superproject with some shallow modules defined in its .gitmodules, then recloning with "--reference=<path>", an error occurs. For example: git clone --recurse-submodules --branch=master -j8 \ https://android.googlesource.com/platform/superproject \ master git clone --recurse-submodules --branch=master -j8 \ https://android.googlesource.com/platform/superproject \ --reference master master2 fails with: fatal: submodule '<snip>' cannot add alternate: reference repository '<snip>' is shallow When a alternate computed from the superproject's alternate cannot be added, whether in this case or another, advise about configuring the "submodule.alternateErrorStrategy" configuration option and using "--reference-if-able" instead of "--reference" when cloning.
