From 070b33da93ad3a191664bb61f5ccc50781460c03 Mon Sep 17 00:00:00 2001 From: Bram Moolenaar Date: Tue, 31 Jan 2017 21:53:39 +0100 Subject: patch 8.0.0274: possible recursive screen updating causes trouble Problem: When update_single_line() is called recursively, or another screen update happens while it is busy, errors may occur. Solution: Check and update updating_screen.
