Raw Normal View History

show --first-parent/-m: do not default to --cc Given that "git show" always shows some diff and does not walk the history by default, it is natural to expect "git show --first-parent" to show the difference between the given commit and its first parent. It also would be natural, given that "--cc" is the default, "git show -m" to show pairwise difference from each of the parents. We however always defaulted to --cc and there was no way to turn it off. Signed-off-by: Junio C Hamano <gitster@pobox.com> 2010-03-09 09:22:54 +01:00			`$ git show --first-parent master`
