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