Now add the syntax parse for the value of `--trailer`: e.g. "Signed-off-by:@Junio", git will fuzzy search in the commit history to find the latest one commit which matches `--author=Junio`, and get the "author " pair `Junio C Hamano ` as the value of `--trailer`, it will be a easy way to add trailers. git commit --trailer` can also benefit from this.
