Increasing the 'Fuzzyness' when matching diffs

[djl197]

When using 'patch' it is possible to increase the fuzzyness. This increases the context range to match hunks (cli flag -F n).
Currently I have an issue where I would like to make diff4j use a wider range when trying to apply patches (I am automating patch application and sometimes the patch does not apply but when using patch with an increased 'fuzzyness' it does.).

Is there any way to set this in diff4j? Or can you point me to where I might 'tweak' the code to increase the range when trying to apply hunks?

Many thanks
