Get -> Returns

I used "Get" to be consistent with the other getters in this file, but I agree
that "Returns" is a better wording. Changed.

+  //
+  // This is the delay introduced by the |blocker_| to be able to get and return
+  // chunks of |chunk_length|, but process blocks of |block_length|.
+  size_t initial_delay() const { return blocker_.initial_delay(); }
+
  private:
   // Internal middleware callback, given to the blocker. Transforms each block
   // and hands it over to the processing method given at construction time.
