Right.

Indeed. This is my current revision of the commit message:

    t1415: avoid using `main` as ref name

    In preparation for a patch series that will change the fall-back for
    `init.defaultBranch` to `main`, let's not use `main` as ref name in this
    test script.

    Otherwise, the `git for-each-ref ... | grep main` which wants to catch
    those refs would also unexpectedly catch `refs/heads/main`.

    Since the refs in question are worktree-local ones (i.e. each worktree
    has their own, just like `HEAD`), and since the test case already uses a
    secondary worktree called "second", let's use the name "first" for those
    refs instead.

    While at it, adjust the test titles that talk about a "repo" when they
    meant a "worktree" instead.

Ciao,
