The subject of "forgot" in that sentence is you, not "git fetch". You told "git fetch" to grab it but not store it locally in your refs/tags namespace.

There is a convenience short-hand "tag <tagname>", i.e.

  git fetch 3rd-repo tag the-tag-name

that is equivalent to

  git fetch 3rd-repo refs/tags/the-tag-name:refs/tags/the-tag-name

So I do not think your patch is necessary for your use case, and obviously it will break other people's use case where they just want to fetch (and inspect what is left in FETCH_HEAD) but do not want to store.
