Well the remote for the submodule is currently only calculated once,
when you do the initial

        git submodule update --init

that clones the submodule. Afterwards the fixed url is configured under
the name 'origin' in the submodule like in a normal git repository that
you have freshly cloned. Which remote is used for cloning depends on the
configured remote for the current branch or 'origin'.

When you do a fetch or push with --recurse-submodules it only executes a
'git fetch' or 'git push' without any specific remote. For fetch the
same commandline options (but only the options) are passed on.

Here it might make sense to guess the remote in the submodule somehow
and not do what fetch without remotes would do.

For the triangular workflow not much work has been done in regards to
submodule support.

But since a submodule behaves like a normal git repository maybe there
is not much work needed and we can just point to the workflow without
submodules most times. We still have to figure that out properly.
