The comment is really just about the inconsistency, not about a request to
have a guaranteed order among the parents of a merge commit.
Having said that, wouldn't it be useful (generally, not just in this
context) to have a guarantee in which order --topo-order lists parents of
a merge?

'git rebase -p z w' is a nonsense request in this situation. (I.e., there
is no requirement on the result.) At best, we could detect it and bail out
or warn.
