   Called when the diff driver wants to report an absent path.

   In case of merges this happens when the diff encounters a server-excluded
   path.

   We register a skipped path, which will make parent mergeinfo non-
   inheritable. This ensures that a future merge might see these skipped
   changes as eligable for merging.
