Please look for END_OF_CASE_TABLE in t/t1000-read-tree-m-3way.sh;
the table talks about some of the (ALT) not implemented, but
some of them are ("git whatchanged t/t1000-read-tree-m-3way"
would tell you which).

Two way cases are described in Documentation/git-read-tree.txt,
if you care.  If you were not touching the three-way case right
now, I'd move/copy the three way cases there as well, but that
can wait until after your changes.
