I don't know git internals, so I can't tell for git. For bzr:
1) You have to add the data to the knits, since the knits are one for
   each versioned file plus one for inventory and one for revision
   metadata, so this is just a small addition to that work. In fact the
   revnos in repository-wide case would be just the indices into the
   revisions knit (while in the branch-wide there would have to be a
   special list).
2) Bzr already generates a special list, revision-history, where it
   stores a list of mainline branches (in fact it used to store a list
   of local commits, but now lists the path over leftmost parents).
   So it already does the work.
