This command can only be used now to list replace refs in "refs/replace/" and to delete them. The option to list replace refs is "-l". The option to delete replace refs is "-d". The behavior should be consistent with how "git tag" and "git branch" are working. The code has been copied from "builtin-tag.c" by Kristian Høgsberg <krh@redhat.com> and Carlos Rica <jasampler@gmail.com> that was itself based on git-tag.sh and mktag.c by Linus Torvalds.
