bug#28959: 25.3; Tramp not honoring `tramp-backup-directory-alist'

[Matz, Daniel A. (JSC-EG511)]

Hello,

Tramp seems to have recently stopped honoring `tramp-backup-directory-alist’.  I have it configured to put all backup files in a single directory:

    (setq tramp-backup-directory-alist '(("." . "/Users/dmatz/.emacs.d/var/backup/“)))

But I’ve started noticing backup files being created on the remote systems, in the same directory as the file I am visiting.

I just tested this with emacs -Q as well, and got the same behavior.

Thanks!

Daniel
