Check local clone
==================

The logic is close enough of uncompressed.
This is present here to reuse the testing around file with "special" names.

  $ hg clone server local-clone
  updating to branch default
  1088 files updated, 0 files merged, 0 files removed, 0 files unresolved

Check that the clone went well

  $ hg verify -R local-clone
  checking changesets
  checking manifests
  crosschecking files in changesets and manifests
  checking files
  checked 3 changesets with 1088 changes to 1088 files

Check uncompressed
==================

Cannot stream clone when server.uncompressed is set
