From 041c98e22d88d963a92f1bac6ab348a0d4c6d228 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sun, 29 Apr 2018 00:44:32 +0200 Subject: [PATCH] replace: prepare create_graft() for converting graft files wholesale When converting all grafts in a graft file to replace refs, and one of them happens to leave the original commit's parents unchanged, we do not want to error out. Instead, we would like to issue a warning. Prepare the create_graft() function for such a use case by adding a `gentle` parameter. If set, we do not return an error when the replace ref is unchanged, but a mere warning.
