test_description='git tar-tree and git get-tar-commit-id test

This test covers the topics of file contents, commit date handling and
commit id embedding:

  The contents of the repository is compared to the extracted tar
  archive.  The repository contains simple text files, symlinks and a
  binary file (/bin/sh).  Only paths shorter than 99 characters are
  used.

  git tar-tree applies the commit date to every file in the archive it
  creates.  The test sets the commit date to a specific value and checks
  if the tar archive contains that value.

  When giving git tar-tree a commit id (in contrast to a tree id) it
  embeds this commit id into the tar archive as a comment.  The test
  checks the ability of git get-tar-commit-id to figure it out from the
  tar file.
