The current code may not put two stage #1 entries for the same path
but allowing such entries was a part of the design from very early
days; iow it is a valid index file, unlike the one that has both
stage #0 and stage #1 for the same path. It is a no-no to reject
such an index as long as we are discussing to add a new code to
tighten the sanity check on the file content.

Yes---that is what I meant by the "virtual stuff". Unlike resolve
work by Daniel (around Sep 2005 $gmane/8088) that tried to use
multiple ancestors directly in a single merge, recursive limits
itself to repeated use of pairwise merges.
