Minor Description
It would be possible to have the contrib/git-hooks/prepare-commit-message script automatically add a Test-Parameters: trivial tag (with an optional testlist=<test> item) to patches that are only modifying test scripts. As with the Signed-off-by: line, this should be added in a commented-out form so that it is up to the developer to determine if this is appropriate, but having the line present would at least remind the user about this option to reduce testing time.
