git-rev-list --date-order ?

Junio,

Gitk has a -d option that tells it to reorder the commits in decreasing order of their commit time, subject to the constraint that parents come after all of their children. Currently it uses git-rev-list --header --topo-order --parents and then reorders the commits internally.

How hard would it be to add a --date-order flag to git-rev-list to make it order the commits in decreasing commit time order, subject to the constraint that parents come after their children?

If we had that then I could remove another chunk of code from gitk and make it a bit faster.

Thanks, Paul.
