Thanks, this version of the patch looks good and is:

    Reviewed-by: Eric Sunshine <sunshine@sunshineco.com>

with or without the minor suggestions below. (If you do re-roll, feel
free to add my Reviewed-by: if you include these suggestions but not
if you make other major changes.)

I realize that this description is just a verbatim copy of what I
suggested during review[1], but in retrospect, I think
s/HEAD/`<branch>`/ would be clearer and more consistent:

    By default, `add` checks out `<branch>`, however, ...

Style: One statement per line, so this should be split over two
lines.

No need for the subshell. This can be written more simply as:

    git -C swamp reset --hard &&
    test_cmp init.t swamp/init.t

Likewise, you can drop the subshell:

    test_cmp init.t swamp2/init.t

For convenience, the above suggestions would look like this (applied
atop your patch). Feel free to fold them in if you re-roll.
