Thanks, makes sense.

I'm fearing that there are more than two.

I can reproduce the issue without submodules and without --local,
as follows:

	git init --bare empty.git
	git init --bare almost-empty.git
	git -C ~/src/git push $(pwd)/almost-empty HEAD:refs/heads/upstream

	git clone --single-branch file://$(pwd)/empty.git
	git clone --single-branch file://$(pwd)/almost-empty.git

	git -C almost-empty.git branch -D upstream

	git -C empty fetch
	git -C almost-empty fetch

Expected result:
Both fetches succeed.

Actual result:
First fetch succeeds, second produces
"fatal: Couldn't find remote ref HEAD".

Note that empty.git and almost-empty.git are basically identical.
The difference instead lies in the clones' .git/config files:

diff --git 1/empty/.git/config 2/almost-empty/.git/config
index b51bb0d..ee21198 100644
--- 1/empty/.git/config
