From 71482d389d0b214d2cfc2adf788ba1011a7dcb18 Mon Sep 17 00:00:00 2001 From: Matthieu Moy Date: Tue, 16 Jul 2013 10:05:37 +0200 Subject: [PATCH] diff: allow --patch & cie to override -s/--no-patch All options that trigger a patch output now override --no-patch. The case of --binary deserves extra attention: the name may suggest that it turns a normal patch into a binary patch, but it actually already enables patch output when normally disabled (e.g. "git log --binary" displays a patch), hence it makes sense for "git show --no-patch --binary" to display the binary patch.
