Differences From Artifact [73d5657b30]:

• File src/leaf.c — part of check-in [69f43fc077] at 2011-01-28 20:56:28 on branch experimental — Add a new meta-data table named LEAF that holds a precomputed set of all leaves in the checkin DAG. Use this precomputed table rather than trying to compute the LEAFs on the fly, as a performance enhancement for repositories with many checkins. A rebuild is required.
