Internally, git-diff-cache -B -C is used which does use the
deltify to locate complete rewrites, renames and copies (that's
why the script is so slow).  For passing on and assigning blames
line by line, parsing "diff --unified=0" output was a lot easier
for this script and that was what I did in this quick-and-dirty
version.

I perhaps phrased it poorly.

The slow part is not a single delta operation, but having to run
many delta operations between all combinations of rename/copy
candidates, which is O(n * m) where n is the number of newly
created files (counting "broken" ones created by -B flag) and m
is the number of (deleted, modified and unmodified) files in the
original tree.
