Overall, the changes made by this patch are valuable since it brings
the script more in line with modern practice and because single-quotes
around the test body make it easier for readers to reason about test
behavior. Coupled with the fact that none of the tests broke by
changing the bodies from double- to single-quote, it's a good idea to
keep this patch in v5 but omit the parts which break the test
descriptions.
