From cc8fef2bddfcf4e1c3bab35a18621dd7666d022e Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Fri, 25 Sep 2020 11:55:51 +0300 Subject: [PATCH] Avoid infinite recursion with 'relative' line numbers display * src/xdisp.c (display_count_lines_visually): Bind 'display-line-numbers' to 'relative' around 'start_display' as well, since that can invoke 'move_it_to' internally, thus causing infinite recursion.
