Ok, you don't add '--init' but the submodule gets checked out,
so it looks like you have 'submodule.active' set to a pathspec
that matches 'sha1collisiondetection'. Did you clone the git repo
with '--recurse-submodules', which would add '.' as the value of
'submodule.active' ? Or maybe you manually configured that value
in your global gitconfig ?

Sry, I did not mention that I started with the submodule already
initialized and checked out. IIRC I deinitialized the submodule with
'git submodule deinit -f sha1collisiondetection/' and ran 'git fetch'
to see if it happens on the git repo, too, since I encountered the
issue on another repo first.

I can see the same misbehaviour when I run
$ git -c submodule.recurse=false fetch --recurse-submodules
too, so I think it doesn't have necessarily something to do with
the 'submodule.recursive' config, but with 'recurse submodules'
in general.
