From e66adcadfe63508dfd7410c2253116043894d298 Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Tue, 7 Feb 2017 01:16:59 -0800 Subject: [PATCH] t7800: simplify basic usage test Use "test_line_count" instead of "wc -l", use "git -C" instead of a subshell, and use test_expect_code when calling difftool. Ease debugging by capturing output into temporary files.
