[PATCH] Add read-tree -m 3-way merge tests.
This adds a set of tests to make sure that requirements on existing cache entries are checked when a read-tree -m 3-way merge is run with an already populated index file. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
