Yay. :)

Not about this patch: if I add more commands before that "diff",
their exit status would be ignored. Could this be made more resilient
using test_expect_code? Something like
test_expect_code 1 git diff --no-prompt --tool=bad-tool branch >actual
&&
>expect &&
test_cmp expect actual
[...]

If this test fails, GIT_DIFF_TOOL would remain set which could take
down later tests, too. Could it be set in a subprocess (e.g., a
subshell) to avoid that?
difftool_test_setup &&
git config --unset diff.tool &&
echo branch >expect &&
GIT_DIFF_TOOL=test-tool git difftool --no-prompt branch >actual &&
test_cmp expect actual

Likewise.

Likewise.

Likewise. This one loses the exit status from 'git difftool',
which could be avoided by writing to temporary files:
echo >input &&
GIT_DIFFTOOL_PROMPT=true git difftool branch <input >output &&
prompt=$(tail -1 <output) &&
[...]

Likewise.
Thanks for cleaning up, and sorry I don't have anything more
substantial to offer.
Hope that helps,
Jonathan
