I might be late for this discussion, but I seem to have
a case when blame --reverse --first-parent seems to work.
I think during the discussion we already established that there are
cases where the mode happens to do the right thing (the most trivial
is a completely linear history).
I do not strongly object to enabling the mode when it is safe to
enable (i.e. it can be proven to work and produce a sensible and
meaningful result); patches welcome to enable it when it can be
shown that it is safe; "to disable it only when it can be shown that
it is meaningless" is a different way to state the same thing.
