I buy this one.

Almost none ;-).

>From reading the code and testing, it affects

$ git fetch
$ cat FETCH_HEAD
...
21d039[...]  not-for-merge  remote-tracking branch 'origin/branch' of /tmp/cloned

when ran in a repository obtained with "git clone --mirror" (i.e. when
you fetch remote-tracking branches from the remote repository).

and

$ git fetch origin refs/remotes/origin/some-branch
From /tmp/cloned
 * remote-tracking branch origin/oaue -> FETCH_HEAD

I don't think any script would parse the last part of FETCH_HEAD,
which seems really to be meant as a comment, nor the precise output of
git-fetch-in-a-mirror-with-refspec-given-explicitely.

But anyway, that's in a place where bare mortals wouldn't go, so I
don't mind much is anyone wants to revert this particular hunk. That's
not going to affect the learning curve of newcommers.

No (that's why it's a separate patch. In case you missed my earlier
message: yes, the testsuite passes between the two).

I've tried a shorter version :

  In the process, we change "non-remote branch" to "branch outside
  the refs/remotes/ hierarchy" to avoid the ugly "non-remote-tracking
  branch". The new formulation actually corresponds to how the code
  detects this case (i.e. prefixcmp(refname, "refs/remotes")).
