From ec0bdb6f1e8fd772ff9eb920ebcb7dd1afcaf362 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 5 Feb 2006 11:42:09 -0800 Subject: [PATCH] diff-tree --always flag It _might_ make sense for certain users like gitk and gitview if we had a single tool that gives --pretty and its diff even if the diff is empty. Having said that, the flag --cc -m is too specific. If some uses want to see the commit log even for an empty diff, that flag should not be something only --cc honors. Here's an "--always" flag that does that.
