branch: emacs-30
commit 7766ba8419955104fb675a6f4134a8a34ea73e43
Author: Thomas Voss <mail@thomasvoss.com>
Commit: Eli Zaretskii <eliz@gnu.org>

    Align columns in which-key with wide characters properly
    
    In the case that a character takes up multple columns (such as
    `…' when used as a truncation character), make sure that the
    columns are still aligned properly.
    * lisp/which-key.el (which-key--pad-column): Use `string-width'
    instead of `length'.  (Bug#73463)
