Yes. I considered it briefly, and it's fixable, but to fix it you'd 
have to actualyl walk the parent list yourself, rather than letting 
get_revision do it all for you.

And what my simple thing shows isn't really technically "wrong", since it 
has shown that there are commits missing from the output with the "..."

The question is just whether shared commits should be "balanced out", or 
shown as part of the first branch that merged them. I chose the latter, 
because it's not only simple, it's unambiguous (any balancing algorithm 
will depend on some random heuristic or other, and on how many commits are 
shown.

Yeah, I actually looked at a few examples, so I knew what it was basically 
trying to do, and then I ignored it as not interesting to the exercise, 
which was to abuse the new revision listing library in interesting ways by 
calling it multiple times.
