git-get-tar-commit-id - Extract commit ID from an archive created using git-archive

       Read a tar archive created by gitarchive from the standard input and extract the commit ID stored in it.
       It reads only the first 1024 bytes of input, thus its runtime is not influenced by the size of the tar
       archive very much.

       If no commit ID is found, gitget-tar-commit-id quietly exits with a return code of 1. This can happen if
       the archive had not been created using gitarchive or if the first parameter of gitarchive had been a
       tree ID instead of a commit ID or tag.
