bug#58525: 28.1: `vc-dir' (key sequence: C-x v d) fails when used with a CVS repository

It appears that `vc-responsible-backend' DOES include the sorting
code that you have described (and which is listed as a patch in
42966).  In fact, that sorting code is included in the excerpt
from that function that I included in my previous message.

The command `emacs-version' reports that it is 28.1.  Also,
/usr/share/emacs/28.1/lisp/vc-dir.el includes the following that all
appear to indicate that the file is from at least 28.1, or later:

  "Face for headers in VC-dir buffers."
  :group 'vc
  :version "28.1")

The problem is fixed for me by removing or renaming my ~/.git/
directory.

To reproduce the problem, create a ~/.git/ directory and then
follow the recipe in the original problem report.  Those steps
take less than 10 minutes to reproduce the problem, using Emacs
28.1, bash, and cvs.  Please let me know if those steps do not
reproduce the problem with Emacs 28.1.
