branch: master
commit 571d802df38cb1d3f93222f2977b766995616ac7
Author: Basil L. Contovounesios <address@hidden>
Commit: Basil L. Contovounesios <address@hidden>
Fix Gnus summary widget navigation across frames
* lisp/gnus/gnus-sum.el (gnus-summary-widget-forward)
(gnus-summary-widget-backward): Signal more informative error if
article window is not found. Consider other frames displaying
article buffer, and raise its frame before navigating its
widgets. (bug#35565)
* lisp/gnus/gnus-win.el (gnus-get-buffer-window): Simplify and add
docstring.
