I was not particularly interested in discussing the initial
merge, which is a perfectly regular merge as you said. I was
more focusing on reusing the tree-structure change information
we _could_ find in merge #3 when we make later merges, because
that merge is something the user did in the past and would be a
good guide for guessing what the user wants to happen to this
There is no question about K in 'keeping addition' case. It
gets interesting only when the first merge prefered 'reject
addition by them' and we would want to reuse that preference in
the second merge. But as I tried to clarify in the "a couple of
things worth mentioning" message, there is no fundamental reason
to treat removal and addition any differently. It is just a way
to reduce unnecessary conflicts.

No question about it again.

Doing this in read-tree is a bit premature. I'd prefer a
scripted solution first to see what we want and how well it
works in practice.

There was another problem in my message that treated #3
specially. I did it that way primarily because I wanted to have
an algorithm that needs to look only limited (namely, one)
number of commits, more than what we currently look at. The
problem is that the trail #0..#1..#3 (in the example in second
message, whose rename probably happened between #0 and #1) may
change the contents of the renamed file so drastically that diff
between #2 and #3 may not look like rename anymore, while we
could still detect it if we followed the whole trail and looked
for renames between each commit on it.
