Hi Philip,

I wish that were the case :) Per the docs:

| given), the commits are shown in reverse chronological order by commit time.

As soon as you specify --no-walk, topological ordering is disabled. I
_think_ it's
because it will instruct `rev-list` not to look at the ancestors. It
looks like a new
in-between option is needed, where topological ordering is used when the dates
match.

Cheers,

Clement
