That's great news, Stefan, and I bow to your perseverance on this. Great work!

I'm sorry I haven't automated generating the table on the
TreeConflictTests wiki page, causing tedious manual work for you. But
I'm glad the page is still useful.

I'll try to do some more manual experiments with a trunk build. I'm
all for rolling an alpha release, or in any case doing what we can to
get user feedback on this.

I'm wondering if we should also create a table / documentation listing
the supported conflict options, and what they do. Or is this more or
less the same as the TreeConflictTests table, since as you said it
covers the existing conflict resolution options?
