The commit 31224cbdc7 (clone: recursive and reference option triggers
submodule alternates, 2016-08-17) argued for any further `submodule update`
to respect the initial setup. This is not the case if you only pass
'--reference[-if-able]' to the initial clone without instructing to
recurse into submodules.
If there are submodules however the user is likely to later run
a 'submodule update --init' to obtain the submodules. In this case we
also want to have the references available.
