I am still interested in the rationale for git-ls-files not supporting
such an option directly, since git-diff still seems a little indirect.

Partly historical, but more fundamental reason is because ls-files
plumbing is about the index.

Added is _not_ about comparision between the index and the work tree.  It
is between the HEAD commit and the index, and it does not belong to
ls-files plumbing.

Also, the following thread may serve as a food for thought; it shows that
there is real need for some concise, easy to parse output for people who
want their own Porcelain.

In short, ls-files and diff-index _can_ give you what you want, but often
people would want information from both, consolidated.
