# result tables for the below tests (trying to make the code more
# simple...) the hash itself represents a request
# the keys to the main hash represent merge levels - 1 for the
# non-overriding merge, 2 for an overriding merge, and 3 for a
# two-level merge the rest should be self-explanatory - settings and
# expected values.
