From d7fb15c822eabe22ffda19892153d69b0f4fc2f3 Mon Sep 17 00:00:00 2001 From: Carlos Garnacho Date: Fri, 3 Apr 2020 12:44:37 +0200 Subject: [PATCH] imwayland: Clamp the surrounding string end correctly In the paths where len > MAX_LEN and cursor/anchor are separated by at least MAX_LEN from text edges, we were clamping the right end of the surrounding string at MAX_LEN. Oops. This end anchor may go as far as the string length, although just up to len - MAX_LEN in real terms (due to the condition above that caches cursor/anchor positions being near enough the text end).
