From 0893eec85fca0f76039a96cbbcd3592ff8571c24 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 29 Mar 2016 15:49:24 -0700 Subject: [PATCH] pretty: enable --expand-tabs by default for selected pretty formats "git log --pretty={medium,full,fuller}" and "git log" by default prepend 4 spaces to the log message, so it makes sense to enable the new "expand-tabs" facility by default for these formats. Add --no-expand-tabs option to override the new default. The change alone breaks a test in t4201 that runs "git shortlog" on the output from "git log", and expects that the output from "git log" does not do such a tab expansion. Adjust the test to explicitly disable expand-tabs with --no-expand-tabs.
