[PATCH] Show dissimilarity index for D and N case.

The way broken deletes and creates are shown in the -p
(diff-patch) output format has become consistent with how
rename/copy edits are shown.  They will show "dissimilarity
index" value, immediately following the "deleted file mode" and
"new file mode" lines.

The git-apply is taught to grok such an extended header.
