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.

Since we already use the name "second" for a secondary worktree that is
created in this test, let's use the name "first" for those refs instead.

While at it, adjust the test titles where "repo" was used by mistake
instead of the term "worktree".

Interesting.  I assume the issue is this line?

	-	git -C fer1/repo for-each-ref --format="%(refname)" | grep main >actual &&

I.e., it's not actually that naming a worktree "main" will break
anything, but just that the test catches refs/heads/main in the same
net when it does grepping?

If the commit message explains that, then this patch looks good to me.
Without such an explanation, it would make me fear that we have some
underlying bug in "git worktree".

Thanks,
Jonathan

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,
Dscho
