bug#40802: 26.3; back-directory-alist ignored

As of Emacs 26.3 on OSX is appears back-directory-alist is
ignored. Auto-save files are no longer going to a tmpdir but are always
saved in the current directory.

I verified this by starting emacs with --no-init-file and setting the
backup-directory-alist manually.

I cannot reproduce this on my system, so it's probably either specific
to OSX or specific to your system.

Is it possible this is because you misspelled backup-directory-alist?

I can't reproduce this on my macOS machine, using "emacs -Q" and:

(setq backup-directory-alist '(("." . "~/backups")))

In GNU Emacs 26.3 (build 1, x86_64-apple-darwin14.5.0, NS

More information was requested, but no response was given within a
year, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.

[Stefan Kangas]

This bug was closed because of a lack of response.  Brett actually got
back to me in April 2020, but it seems like he didn't use "Reply to
all", so it never reached the bug tracker.  I have included his full
message below.

I'll leave it to you to decide if this means the bug should be re-opened or not.

Nope, sorry - I just mis-typed it in this email subject. My literal config is:
(setq backup-directory-alist
      `((".*" . ,temporary-file-directory)))
(setq auto-save-file-name-transforms
      `((".*" ,temporary-file-directory t)))

I ran emacs with --no-init-file then set this config manually using
eval-expression. I still observe autobackup files in my current
directory. I also observed that temporary-file-directory exists and
emacs is writing other types of files there.

I'm unable to reproduce this in Emacs 26.1 or Emacs 28 (I don't have
Emacs 26.3 here).

With this conf, all the backup files end up in /tmp/ with names like

  -rw-r--r--  1 larsi      larsi             7 Aug 25 12:42 !home!larsi!tmp!foo~

as expected.
