Thanks for this. I distilled your example into a shell script that uses
git, and demonstrates that git gets the merge wrong:
Still, git could get this merge right, it just doesn't (I know there are
more complex cases that would be very hard for git to get right). I
suspect that in practice this rarely matters, because context-based
merging usually does the right thing.
