  merge: use annotated commits for recursion
  
  Use annotated commits to act as our virtual bases, instead of regular
  commits, to avoid polluting the odb with virtual base commits and
  trees.  Instead, build an annotated commit with an index and pointers
  to the commits that it was merged from.
