[PATCH] cg-admin-rewritehist: fix reappearing files with --filter-tree.

[Johannes Sixt <johannes.sixt@telecom.at>]

With --filter-tree a working copy is checked out for each commit.
However, if a file is removed by a commit, the file is _not_ removed
from the working copy by git-checkout-index. This must be done explicitly,
otherwise the file becomes added back again.
