git-svn: exclude already merged tips using one rev-list call
The old function would have to check all mentioned merge tips, every time
that the mergeinfo ticket changed. This involved 1-2 rev-list operation
for each listed mergeinfo line. If there are a lot of feature branches
being merged into a trunk, this makes for a very expensive operation for
detecting the new parents on every merge.
This new version first uses a single 'rev-list' to figure out which commit
ranges are already reachable from the parents. This is used to eliminate
the already merged branches from the list.
