 The FILTER string is tested against the name of all tests, and only those
-tests whose names contain the filter are run.
+tests whose names contain the filter are run. Multiple filter strings may

 By default, all tests are run in parallel. This can be altered with the
 --test-threads flag or the RUST_TEST_THREADS environment variable when running
