Thank you Stephen.

The two emacs repairs (find-dired-refine-function and find-dired-filter) you sent worked for me.

The aspell I pushed a bit farther.  In 2015 I replaced the aspell (dated 2009) in /usr/local/bin with something from homebrew.
I remember no details.  When I installed the new M1, the Apple installation process automatically copied everything from the old machine,
including the homebrew aspell and my subdirectory containing the 2009 files.
If there had been an Apple M1 aspell, it was overridden.  Based on Vincent Goulet's notes, there might
not have been one, and in any case he recommends hunspell.  I will address the spelling problem soon, but not today.

Rich

The NEWS file in Emacs 27 says:

  ** The 'cl' package is now officially deprecated in favor of 'cl-lib'.

The NEWS file in Emacs 27 says:

  *** New user option 'find-dired-refine-function'.
  The default value is 'find-dired-sort-by-filename'.

So you can prevent the resorting by setting find-dired-refine-function
to nil (by setq in your init file or by `M-x customize-option').

When I try your find-dired string in emacs-27 (and also in emacs-28) I
also get an error in process sentinel, but a different one:
"find-dired-filter: Invalid use of ‘\’ in replacement text".  This
appears to be due to this change:

    Fix output alignment in 'find-dired' for "ls -h"

    * lisp/find-dired.el (find-dired-filter): Fix alignment of
    the file size column when the -h ls option is used in
    'find-ls-option'.  (Bug#29803)

When I revert this change (by replacing `^[:space:]' by `0-9' in the
above code excerpt), I don't get the error anymore.  Since the error
message you got is different, it may have a different cause.  In any
case, it looks like it warrents a bug report (`M-x report-emacs-bug').

I can't help with this one, but maybe it's also worth a bug report.
