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.
