When it is run in a worktree 'git for-each-ref' only seems to show refs
under refs/rewritten if that directory also exists under $GIT_COMMON_DIR
even though they are local to the worktree.
Initially I thought this was due to $GIT_COMMON_DIR pointing to a bare
repo, but that is not the case. However while writing a test case which
cloned to a bare repo I noticed it was listing a ref for the HEAD of a
worktree in the repo I had cloned from, not the clone itself.
The script below reproduces both issues, I've copied the output below
it. I'm not sure what's going on or the best way to debug it.
Best Wishes
