You can't. It's fundamentally not doable, because you lose the merge information.

So you need to use a combination of git-rev-list _and_ git-whatchanged.

Use the "--parents" flag to git-rev-list to get the parents output for doing your own graph, if you want to.

I have been thinking of adding a "follow this file" mode to git-rev-list, which just ignores all children of merges that used the file directly from one of the other children. Exactly because then you could have a git-rev-list that prunes based on filename, and would potentially be a lot more efficient (not follow the "uninteresting" side of a merge).

I haven't gotten around to it, partly because I wonder if it would be better as a separate program - even if that would mean that you'd lose all the cool features of git-rev-list (the ability to limit it to certain versions, and the ability to sort the output in relevant orders).

Partly because I'm just too friggin lazy.

Nope, this is a direct result of two branches modifying the same file in parallel. There is no "right" or "wrong" order.
