From ec3cc27ab06c0b7ebaf9aee3eaa6e35719eef8da Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Mon, 13 Sep 2021 05:35:37 +0200 Subject: [PATCH] difftool: prepare "struct child_process" in cmd_difftool() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the preparation of the "struct child_process" from run_dir_diff() to its only caller, cmd_difftool(). This is in preparation for migrating run_file_diff() to using the run_command() API directly, and to move more of the shared setup of the two to cmd_difftool().
