When running git rev-list --all --reflog in the main worktree it doesn't
include commits only referenced by the worktrees, neither HEAD nor its
reflog.
$ git init test
$ cd test
# add some commits
$ touch 1; git add 1; git commit -m 1
$ touch 2; git add 2; git commit -m 2
# add new worktree
$ git worktree add ../test2 master^{}
$ cd ../test2
# add more commits
$ touch 3; git add 3; git commit -m 3
$ touch 4; git add 4; git commit -m 4
# create an unreferenced commit
$ git checkout @^
# both commands should give the same number of commits
$ git rev-list --reflog | wc -l
4
$ git -C ../test rev-list --all --reflog | wc -l
2
IIUC this will cause git gc to prune references from worktrees too
early.
