use literal quoting in metaprogramming tests

[ichthyo]

The metaprogramming unit tests would especially benefit from judicious use both of the regexp facility of test.sh, as well of the (planned as of 6/09) possibility to quote expected output literally within the test definition. The reason being these tests are to build a structured test type, which just reports its structure on construction, and the exact structure of this output is what has to be covered by the test.
