This makes sense.  I got confused every time I had to "append to tail"
and had to draw boxes-and-arrows picture to make sure I understand how
to use "\(.*\) = &commit_list_insert(something, \1)->next" correctly.

There probably are tons of places that can use this thing.

    $ git grep -c -e '\&commit_list_insert(.*)->next'
    builtin/commit.c:4
    builtin/diff-tree.c:1
    builtin/merge.c:3
    commit.c:4
    revision.c:5

I however wonder if we can name "next" a bit better, but cannot come up
with a good name.  It is the location that holds the pointer to the new
tail element if we append one.  Some places may call it "tail" but that
gives a wrong impression that it points at the element at the end.
