> Hey, all.  Per the subject line, I noticed that this display action
> function isn't respecting when I mark a window dedicated to its buffer.
> 
> Here's a minimal example you can step through in the scratch buffer:
> 
> ```
> (setq *w* (split-window-horizontally)
>       *one* (get-buffer-create "one")
>       *two* (get-buffer-create "two"))
> 
> (display-buffer-use-some-window *one* '((inhibit-same-window . t)))
> ;;; should see "one" appear in the *w* window
> 
> (set-window-dedicated-p *w* t)
> (display-buffer-use-some-window *two* '((inhibit-same-window . t)))
> ;;; should not see any changes, the function returns nil
> (display-buffer-reuse-mode-window *two* '((inhibit-same-window . t)))
> ;;; bug -- should see "two" appear in the *w* window
> ```

> I think this is a bug in -reuse-mode-window, and so I've attached a
> patch that would fix the issue.  Though maybe I'm wrong?  Is
> this intended behavior?
