Seeing added and removed files between two tree states

In there a way to see just what files where added between two points in
the tree? I want something better than parsing the diffstat.

I thought git-ls-files -ad comittish..comitishb would do the trick but
it seems not.

[spearce@pb15 git]$ git diff-tree -r --abbrev --diff-filter=A next build
:000000 100644 0000000... 3d53d17... A  shallow.c
:000000 100644 0000000... 1fe7a1b... A  xdiff/xmerge.c
