This patch fixes the issue by specifying Z_DEFAULT_COMPRESSION.

 /* Try to guess the requested revision from the requested snapshot name.

  * "cgit-0.7.2". If this is a valid commit object name we've got a winner.
  * Otherwise, if the snapshot name has a prefix matching the result from
  * repo_basename(), we strip the basename and any following '-' and '_'
  * characters ("cgit-0.7.2" -> "0.7.2") and check the resulting name once
  * more. If this still isn't a valid commit object name, we check if pre-
  * pending a 'v' to the remaining snapshot name ("0.7.2" -> "v0.7.2") gives
  * us something valid.
