Merge code duplicates by equivalent code fragment

I use phpcpd with Jenkins plugin DRY.
 
After build job, i got this result:
```

Found 120 exact clones with 11743 duplicated lines in 151 files:

But DRY report includes only 8 files.

For fix this, i merge code duplicates by code fragment.

Job result after fix:
```

```
 
Now DRY show all 10 files.

I think that this kind of output is more informative.
