Possible Bug with `git commit -a` in v2.41.0

Possible Bug with `git commit -a` in v2.41.0

[Dylan Brotherston]

`git commit -a` is unable to remove the last file in the index in v2.41.0

 

comparing git version 2.30.2 to 2.41.0

 

```

$ git --version

git version 2.30.2

$ git init

Initialized empty Git repository in /tmp/tmp.vXqq6iVaqq/.git/

$ echo "foo" > a

$ git add a

$ git commit -m "C1"

[master (root-commit) b3abdc4] C1

 1 file changed, 1 insertion(+)

 create mode 100644 a

$ rm a

$ git commit -a -m "C2"

[master c3d4c44] C2

 1 file changed, 1 deletion(-)

 delete mode 100644 a

```

 

```

$ git --version

git version 2.41.0

$ git init

Initialized empty Git repository in /tmp/tmp.vXqq6iVaqq/.git/

$ echo "foo" > a

$ git add a

$ git commit -m "C1"

[master (root-commit) af7c07d] C1

 1 file changed, 1 insertion(+)

 create mode 100644 a

$ rm a

$ git commit -a -m "C2"

On branch master

Changes not staged for commit:

  (use "git add/rm <file>..." to update what will be committed)

  (use "git restore <file>..." to discard changes in working directory)

        deleted:    a

 

no changes added to commit (use "git add" and/or "git commit -a")

```

Thanks for an easy reproduction recipe. I think this bug has already
been fixed by 2ee045eea1 (commit -a -m: allow the top-level tree to
become empty again, 2023-06-29). That's currently in 'next', and slated
to merge to 'master' soon (and hopefully will make it to 'maint' for
a v2.41.1 release).
