From f67986b9098c21005f33182472a990d5c6e8a98d Mon Sep 17 00:00:00 2001 From: Michael J Gruber Date: Fri, 19 Jun 2015 11:30:55 +0200 Subject: [PATCH] mergetool-lib: fix default tool selection When no diff nor merge tool is specified (config, option), mergetool-lib is supposed to choose a default tool from a set of tools. That set is constructed dynamically depending on the environment (graphical, editor setting) as a space separated string of tool names. 719518f (mergetool--lib: set IFS for difftool and mergetool, 2015-05-20) introduced a newline as IFS which breaks the parsing of the space separated list into items, resulting in a failed search for an available tool. Set IFS to a space locally for the tool search.
