Yeah, the reverted 83c9031 (unpack_trees(): skip trees that are the same
in all input, 2010-12-22) also seems to have seriously broken intermediate
merge merge-recursive makes.  I actually recall scratching my head when I
made 00e6ee7 (Merge branch 'maint', 2011-02-11) that was causing add/add
conflict when it shouldn't.  It turns out that quite a lot of entries were
missing in contrib/ area from the virtual common ancestry tree synthesized
by merge-recursive that called into the botched unpack_trees()---it of
course would result in add/add conflict if a merge is done using such a
tree as the common.

No, I haven't had a chance nor energy to dig further than what I reported
above.
