If a duplicate entry is found, rule_map_cmp() incorrectly
assumes that the lengths of the key value pairs should be
equal, when this is not true. The duplicate detection is
done on the input parameters, thus the lengths can be
different. This resulted in a duplicate error string
message of "do not match", instead of "match on all inputs".

Also, the file name printed that contained the error was
the output file, not the input file that contained it.
