The four commit series starting at 4c4caaf fixed a few D/F
conflict case in merge recursive.
4c4caaf... Treat D/F conflict entry more carefully in unpack-tree...
ac7f0f4... merge-recursive: do not barf on "to be removed" entries.
4d50895... merge-recursive: handle D/F conflict case more carefully.
885b981... t3030: merge-recursive backend test.
However this ended up regressed the following case (don't bother
bisecting, it will point at 4c4caaf).
The test case starts with a tree with a directory at D/,
one branch (master) modifies files in it, while the other branch
(side) makes a bunch of rename and has a blob at D.A, D, and D0C
Yes, this does not trigger if you change D.A to DxA (anything
that does not sort before D/ in the index).
Anybody interested in figuring out how to fix unpack-trees.c
without breaking the problem the above series fixed?
