REVISION SUMMARY
  We have more and more requirement that does not affect revlog or that only
  affect some of them. It is silly to force a full processing of all revlog to
  juste move the requirement around, or to simply rewrite the dirstate.
  
  So now, only the revlog that needs to be touched will be touched. Unless the
  --changelog & al flags are used.
