Here's most of the patch :

+      (`manly
+       (and (frame-live-p saved-frame)
+            (select-frame saved-frame))
+       (if-let ((window (seq-some-p
+                         (lambda (window)
+                           (with-current-buffer (window-buffer window)
+                             (derived-mode-p 'Man-mode)))
+                         (window-list))))
+           (set-window-buffer window man-buffer)
+         (display-buffer man-buffer)))

Sure, why not!

That was not intended. I probably hit R instead of F, sorry about that.

Nico.
