It seems sensible to use the test files that I wrote for MERGE in 2008,
published to -hackers at that time.

The tests were a complete output from a MERGE test script. 

Developing new tests when we already have code makes little sense, plus
its a good way of objectively testing that the spec has been implemented
correctly in these patches.
