This approach with a custom merge strategy is very much closer to what feels like it will work best. I just gave this a try, and I seem to be falling at somewhat the first hurdle. I have a custom merge strategy working, insofar as I've written a script that is being called. The script simply wraps "git merge-ort" as you suggest. But I can't seem to work out how to actually run 'git merge-ort'! I've tried 'git merge -s "$@"' in my wrapper script, but doing so my custom strategy behaves differently to if I use no strategy, which seems to suggest I'm doing something wrong. Do you have any suggestions/pointers? Best, Paul
