What is "this"???

So far, "git replace -d <rev>" only accepts a full sha1, because it uses
it literally as a ref name "resf/replace/<rev>" without resolving anything.

The patch makes it so that <rev> gets resolved to a sha1 even if it is
abbreviated, and then it gets used.

Or do you mean the warning?
