Subject: bug#78186: 31.0.50; Register Selection Broken
Date: Thu, 01 May 2025 12:14:30 +0000

If the user has customised `register-use-preview', selecting a register,
e.g. via `jump-to-register' errors with "No suitable register".  It
appears this due to changes to recent changes in register.el (I believe
b2904e06 is specifically the critical commit), so I've CC'ed Stefan in
case he has anything to add.

To reproduce the issue from master, start "emacs -Q", evaluate

  (setopt register-use-preview 'never)
  (set-register ?h  '(file . "~"))

and then invoke `jump-to-register'.  This should fail.
