From 8f3bf4f0d3605b50a8e4c48c89aeabc455f04884 Mon Sep 17 00:00:00 2001 From: Yousong Zhou Date: Fri, 24 Mar 2017 21:13:10 +0100 Subject: vi: avoid touching a new file with ZZ when no editing has been done This is the behaviour observed with standard vim and busybox vi of at least 1.22.1. It was changed with commit "32afd3a vi: some simplifications" which happened before 1.23.0. Mistyping filename on command line happens fairly often and it's better we restore the old behaviour to avoid a few unnecessary flash writes and sometimes efforts of debugging bugs caused by those unneeded stray files.
