Cool, I'll file this under modernizing the test infrastructure ;-)

Up to here we unwrapped code and removed test_expect_success
and just executed the code as is, so later callers would need to encapsulate
the call to check_tar with test_expect_success.

However as we are touching the code here, we can go further than just
unwrapping it, usually we'd format one command a line,

    (
        cd ${dir_with_prefix}a &&
        find .
    ) | sort >$listfile &&
    test_cmp ...

I am not sure if that standard style is more legible in this case though.

Heh. Just looked into the file and the surrounding code is
a wild mixture of the old style

test_expect_success \
    'git archive' \
    'git archive HEAD >b.tar'

check_tar b

and the new style

test_expect_success 'test name' '
 <TAB> command &&
 <TAB> command2
'

Maybe we could cleanup that file to look more like
one of the newer tests (e.g. t3206, t0410) ?

But I guess for the purpose of getting the check_tar
function usable inside a test, this would do enough.

In new style this would look like

    test_expect_success 'extract with olde- prefix' '
        check_tar with_olde-prefix olde-
    '
