* Sorts changes to apply to a file by position in the file in descending order.
* So changes are applied from end to start of the file.
*
* This is important, as if applying changes in any order, it can happen that changes are messed up.
* For instance, if removing some characters first, and then applying a replacement later.
* If later replacement doesn't take into account that position has been updated due to the delete,
* Then the actual replacement performed won't be the expected one.
*
* See:
