Re: [PATCH 0/6] t5000: add test for pax extended header generation

> This series adds a test that exercises git archive's pax header code.
> It checks for tar versions that don't support pax headers and works
> around their deficiency.
>
> The first five patches are cleanups and refactorings to centralize
> tar calls into a helper function.  The last patch adds the workaround
> at this central place and a file to the test archive whose name is too
> long to fit into the path field of a standard tar header, making a pax
> extended header necessary.
