From e90c853ff6dcef63bff80be0e7379a80c276af8f Mon Sep 17 00:00:00 2001 From: Bram Moolenaar Date: Wed, 5 Nov 2014 16:03:44 +0100 Subject: [PATCH] updated for version 7.4.499 Problem: substitute() can be slow with long strings. Solution: Store a pointer to the end, instead of calling strlen() every time.
