I have not done yet, but I do use git for my org repo; however, I commit
every 6 hours via cron (and the commit message is a timestamp). I'm
planning to do something similar to what you described, but I haven't used
org-merged-driver yet. I'll play with it and post my findings, if you do,
let us know how it goes as well!
