BUG in fetching non-checked out submodule

Hi,

I have the current 'master' branch of git installed and get the following error when fetching a submodule that is not checked out.

I've bisected this error down to commit 1b7ac4e6d4 (submodules: fix of regression on fetching of non-init subsub-repo, 2020-11-12)

$ git version git version 2.29.2.435.g72ffeb997e

$ git config --get submodule.recurse true

$ git submodule status -855827c583bc30645ba427885caa40c5b81764d2 sha1collisiondetection

$ git fetch Fetching submodule sha1collisiondetection Fetching submodule sha1collisiondetection/sha1collisiondetection Fetching submodule sha1collisiondetection/sha1collisiondetection/sha1collisiondetection Fetching submodule sha1collisiondetection/sha1collisiondetection/sha1collisiondetection/sha1collisiondetection ...

$ git submodule update --checkout Submodule path 'sha1collisiondetection': checked out '855827c583bc30645ba427885caa40c5b81764d2'

$ git fetch Fetching submodule sha1collisiondetection $
