Ah, good. It is still an experiment, as far as I'm concerned. Alas, I haven't gotten round to look at it, really.

We were discussing this, Jonathan Nieder had two more suggestions/ideas

    http://kerneltrap.org/mailarchive/git/2008/8/15/2954214
    http://kerneltrap.org/mailarchive/git/2008/8/15/2952004

and Bert reported a bug

    http://kerneltrap.org/mailarchive/git/2008/9/1/3152864

The last implementation would just recreate a branch with all new dependencies, which is quite inefficient when you're just removing or adding one (and the list of dependencies is long, say ~100).

It would be nice if my previous cherry-pick & revert logic would be combined with git read-tree to create the new dependencies-base. That could be much faster and hopefully git read-tree could fix the multiple add/remove issue.

Greetings, Jan.
