With this patch it is possible to specify a co-author when committing. You'd just need to provide the --coauthor argument with a co-author in the format "Co Artur <co-ar...@example.com>". You can specify multiple co-authors by using the --coauthor argument multiple times.
The Co-authored-by trailer is something that is commonly used when people pair up and want multiple authors in the commit message.
