[PATCH 0/3] commit -a -m: allow the top-level tree to become empty again

This patch series is in response to the bug report in https://github.com/git-for-windows/git/issues/4462 that demonstrates that git commit -a -m <msg> would no longer always stage all updates to tracked files. The bug has been introduced in Git v2.40.0.

Johannes Schindelin (3):
  do_read_index(): always mark index as initialized unless erroring out
  split-index: accept that a base index can be empty
  commit -a -m: allow the top-level tree to become empty again
