Re: [PATCH 6/6] clone: reference flag is used for submodules as well

Stefan Beller [off-list ref] writes:

When giving a --reference while also giving --recurse, the alternates
for the submodules are assumed to be in the superproject as well.

In case they are not, we error out when cloning the submodule.
However the update command succeeds as usual (with no alternates).

I covered most of what I want to say on this in my reply to 0/6; I
do not have strong objection against what single layout you chose to
support, nor I have strong opinion on which single layout we should
support by default, or what mechanism, if any, we should give users
to specify different layout.

But please make sure the choice you made is explained for the users.
The end-user documentation should talk about the effect of giving
these two options together.

Thanks.
