[PATCH v3 2/4] history: give commit_tree_ext a message template

From: Harald Nordgren <redacted> commit_tree_ext() reuses the message of the commit it is handed. A caller that folds several commits together wants to seed the message from more than that single commit, so add an optional message_template parameter. When NULL, the behavior is unchanged. Pass NULL from the existing fixup and split callers. Signed-off-by: Harald Nordgren <redacted> --- builtin/history.c | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-)
