Subject: Ignore dedicated windows in 'display-buffer-reuse-mode-window'
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9e2bf138cbe72147b7250082f050d5bddad230e2;p=emacs.git

Ignore dedicated windows in 'display-buffer-reuse-mode-window'

Ignore the dedicated windows unless the dedicated window is
already displaying the buffer-to-be-displayed.  In that case,
the window may be reused, according to the setting of
'inhibit-same-window'.
* lisp/window.el (display-buffer-reuse-mode-window): Check
'window-dedicated-p' before pushing the candidate window onto
the stack.  (Bug#76216)

(cherry picked from commit b6efedd66a08103e547266279419e646fc659339)
