test_description='parallel-checkout: attributes

Verify that parallel-checkout correctly creates files that require
conversions, as specified in .gitattributes. The main point here is
to check that the conv_attr data is correctly sent to the workers
and that it contains sufficient information to smudge files
properly (without access to the index or attribute stack).
