# 'combinations' is a list of lists of codes to merge together. The earlier
# codes will take priority, so if all are found, only the first one will be
# left after blending.
#
# Note that since not all tools will necessarily be run, the first message for
# a line as sorted by the code list will be the one remaining after blending.
