Re: [PATCH v2 0/8] Various fixes for v2.45.1 and friends

[Junio C Hamano <gitster@pobox.com>]

I have applied this to maint-2.39 and then merged them up to the
maintenance tracks.  The results will be pushed out to the "split
out" repository at

    https://github.com/gitster/git/

as these branches:

    js/fix-clone-w-hooks-2.39
    js/fix-clone-w-hooks-2.40
    js/fix-clone-w-hooks-2.41
    js/fix-clone-w-hooks-2.42
    js/fix-clone-w-hooks-2.43
    js/fix-clone-w-hooks-2.44
    js/fix-clone-w-hooks-2.45

For those who are merging them up at home yourselves, here are the
remerge diff that show the conflict resolution I made.
