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

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

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.

René Scharfe (6):
  t5000: integrate export-subst tests into regular tests
  t5000, t5003: create directories for extracted files lazily
  t5000: factor out check_tar
  t5000: use check_tar for prefix test
  t5000: simplify tar-tree tests
  t5000: test long filenames
