The report has redundancies for groups of 3+

[larrykollar]

If there is a group of three or more matches, like this:

Matches for file1.txt block 3:
foo bar baz
    file2.txt block 7 (ratio 1):
    foo bar baz
    flle3.txt block 12 (ratio 1):
    foo bar baz

Then there will be a redundant group all but the first match:

Matches for file2.txt block 7:
foo bar baz
    flle3.txt block 12 (ratio 1):
    foo bar baz

A second script, that takes the piped input from the report, would be a good way to weed out redundant groups.
