From 698ce6f87e0d6db380f7306e190e8586da184577 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sat, 20 May 2006 15:40:29 +0200 Subject: [PATCH 1/1] fmt-patch: Support --attach This patch touches a couple of files, because it adds options to print a custom text just after the subject of a commit, and just after the diffstat. [jc: made "many dashes" used as the boundary leader into a single variable, to reduce the possibility of later tweaks to miscount the number of dashes to break it.] Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano --- builtin-log.c | 17 ++++++++++++++--- builtin-rev-list.c | 2 +- commit.c | 10 +++++++++- commit.h | 2 +- diff.c | 6 +++++- diff.h | 3 +++ log-tree.c | 37 +++++++++++++++++++++++++++++++++---- revision.h | 1 + show-branch.c | 2 +- 9 files changed, 68 insertions(+), 12 deletions(-) diff --git a/builtin-log.c b/builtin-log.c index 12a6d192..c8feb0f7 100644 --- a/builtin-log.c +++ b/builtin-log.c @@ -183,7 +183,12 @@ int cmd_format_patch(int argc, const char **argv, char **envp) argv[i + 1]);
