Subject: bug#46876: [PATCH] Find conflict markers in opened buffers as well

From: Konstantin Kharlamov <[email-masked]>
Date: Tue, 2 Mar 2021 19:23:49 +0300

Call to (vc-find-conflicted-file) will only result in jump to a conflict
marker when file is a newly opened one. When a file is already open in
Emacs, (vc-find-conflicted-file) only switches to that buffer, so we
need to explicitly jump to a conflict marker.

* lisp/vc/smerge-mode.el (smerge-vc-next-conflict): Search for a
conflict marker if call to (vc-find-conflicted-file) haven't resulted in
a jump to one.
