  • Committer: Martin Pool
  • Date: 2005-08-25 05:58:05 UTC
  • mfrom: (974.1.36)
  • Revision ID: mbp@sourcefrog.net-20050825055805-8c892bc3c2d75131
- merge aaron's merge improvements:

  * When merging, pull in all missing revisions from the source
    branch. 

  * Detect common ancestors by looking at the whole ancestry graph, 
    rather than just mainline history.

  Some changes to reconcile this with parallel updates to the test and
  trace code.
