me too.
But on the other hand I do not want to offend non-submodule-gitlink-users
too much. So maybe:
$ git add <gitlink>
# Adding a raw gitlink to the index,
# in case you want to use a submodule,
# use add a .gitmodules file or use 'git submodule add'

but these are the 2nd step, clone fails first.

But the user would never learn, because
$ git clone --recurse-submodules ...
does not complain, but put an empty dir instead.
