25.0.50; [PATCH] Allow M-x man to reuse an existing window |

When running M-x man RET man RET, then C-x o to select the newly created
window and then running M-x man RET sed RET, what you get is: two "man"
windows side by side. It would make sense to re-use the existing one.
How to best do that I do not know. If modifying the code is necessary,
here's an attempt at adding an option in Man-notify-method. (I'm not
attached to this implementation, and even less attached to the silly
name `manly' that I chose, btw.)

Subject: [PATCH] Allow M-x man to reuse an existing window
* man.el (Man-notify-when-ready): add `manly' option.
(Man-notify-method): augment docstring accordingly.

Thanks for your review, martin. I pushed the modified commit to master
as 2d382515bfdb44d585bda6515f8d03f9056a83ef.
I'm marking this bug as done since one can now do
(setq display-buffer-alist
(list
(cons "\\`\\*Man .*\\*\\'"
(cons
#'display-buffer-reuse-mode-window
'((inhibit-same-window . nil))))))
to get the effect mentionned in the initial report.
