Fix: enable the approval of the output of a test that is expected to complete but produces the incorrect output. Running the approve subcommand on such a test now successfully changes its status from XFAIL to XPASS (#103).
Allow multiple -s search queries in the same test command, allowing the selection of various tests by their name or hash (#110).
Add a --expert option to hide the legend printed by run and status (#109).
Add a --autoclean option to run and status subcommands to delete test snapshots that don't belong to any known test as it typically happens after tests are renamed (#126).
