I think you're right that dropping the "don't follow off-graph
treesame parents" rule would be a sensible change. The usual point of
the "follow the treesame parent" rule is to avoid drawing undue
attention to merges of ancient history where some of the parents are
side-branches with an old version of the files being tracked and did
not actually change those files. That rationale applies just as much
for a merge on top of an UNINTERESTING rev as any other merge.
Sounds sensible. Thanks.
