Or truncated lines could be enabled by default in the "Dired help"
buffer by using (setq truncate-lines nil)

Wouldn't ‘C-x <’ and ‘C-x >’ be more needed to scroll the minibuffer
horizontally?  I tried to toggle truncated lines in the minibuffer,
and then ‘C-x <’ and ‘C-x >’ scroll the minibuffer horizontally.
