* build-aux/test-driver.scm (show-help): Add the help text for the new '--errors-only' option. (%options): Add the errors-only option. (test-runner-gnu): Add the errors-only? parameter and update doc. Move the logging of the test data after the test has completed, so a choice can be made whether to keep it or discard it based on the value of the test result. (main): Pass the errors-only? option to the driver. * doc/guix.texi (Running the Test Suite): Document the new option.
