Follow-up 465028e0e2 (merge: add missing strbuf_release(),
2021-10-07) and address the "msg" memory leak in this block. We could
free "&msg" before the "goto done" here, but even better is to avoid
allocating it in the first place.
By repeating the "Fast-forward" string here we can avoid using a
"struct strbuf" altogether.
