I'm *guessing* that this apparent exception to the stated rules could be because Q is the start of the walk. Or maybe I'm just missing a key detail. I'd love to hear confirmation either way.

[Questions 2 and 3 snipped]

4. --dense (the default behaviour) includes walked commits iff they are not
   TREESAME to any parent.  --sparse includes all walked commits.  But
   how do I get the middle ground, i.e. all walked commits which are
   not TREESAME to at least one parent?

This seems like an obvious use case, but I haven't figured out how to do it yet :-/

Thanks! (I probably don't say that often enough, but the sentiment is always there ;-)
