 * Optimize BufferModificationListener behaviour:
+
   - Editor should modify in reverse order, as a modification at one point does not
     impact the position of selections before it, so applying modification in reverse
     order removes the needs to have selection updated on the fly, and permit deferred
     update.

   - Accumulate all the modifications and update the selections with the
     whole knowledge -> try to remove this O(n2) behaviour.
