get_sha1: warn about full or short object names that look like refs
When we get 40 hex digits, we immediately assume it's an SHA-1. This is the right thing to do because we have no way else to specify an object. If there is a ref with the same object name, it will be ignored. Warn the user about this case because the ref with full object name is likely a mistake, for example git checkout -b $empty_var $(git rev-parse something) advice.object_name_warning is not documented because frankly people should not be aware about it until they encounter this situation. While at there, warn about ambiguation with abbreviated SHA-1 too. Signed-off-by: Nguyễn Thái Ngọc Duy <> Signed-off-by: Junio C Hamano <>
