Method compact_diff3

  `array(array(array)) compact_diff3(array a, array b, array old)`

Description

  Given three arrays like those returned from diff3 , this function "compacts" the diff3 result by removing all differences where `a` and `b` agrees against `old`. The result is on the same form as the result from diff , and doesn't include the sequence from `old`.
