  66# This test with clone --mirror checks for possible regressions in clone
  67# or the machinery underneath it. It ensures that no future change
  68# causes clone to ignore refs in refs/namespaces/*. In particular, it
  69# protects against a regression caused by any future change to the refs
  70# machinery that might cause it to ignore refs outside of refs/heads/*
  71# or refs/tags/*. More generally, this test also checks the high-level
  72# functionality of using clone --mirror to back up a set of repos hosted
  73# in the namespaces of a single repo.
