[PATCH] Add more tests for read-tree --emu23.
This adds more tests for --emu23. One is to show how it can carry forward more local changes than the straightforward two-way fast forward, and another is to show the recent overeager optimization of directory/file conflict check broke things, which will be fixed in the next commit.
