Maybe we could add something like ‘display-buffer-reuse-mode-window’ to
window.el. In that case I'd proceed as follows:
(1) The frame(s) to scan for a suitable window should be determined by a
‘reusable-frames’ entry just as in ‘display-buffer-reuse-window’.
(2) Allow to specify the desired (parent) mode via an ALIST ‘mode’
entry. As value we could allow a single mode or a list of modes. Then
a window showing a buffer in the same mode as the buffer we want to
display should maybe given preference to a window showing a buffer in
another mode, derived from the same parent mode. If a same-mode-window
exists on another and a derived-mode-window exists on the selected
frame, one of these should be given preference consistently.
(3) Not use functions like ‘if-let’ and ‘seq-some-p’. window.el is
preloaded and if not utterly necessary I'd prefer not loading subr-x.el
there. BTW, I have no idea from where you get ‘seq-some-p’. Did you
compile your patched man.el with emacs -Q?
WDYT?
