When the output mode is, say, `DIFF_FORMAT_PATCH`, the `diff_fill_oid_info()` function, called from `run_diff()`, will remedy that situation by reading the file contents from disk. However, when the output mode is `DIFF_FORMAT_RAW`, that does not hold true, and the output will contain a bogus OID (and the flag `M` for "modified" instead of the correct `A` for "added"). As a consequence, `git difftool -d` (which relies on `git diff-files --raw`'s output) does not work correctly. Let's fix this specifically by imitating `diff_fill_oid_info()`. Note: we can only do that for diff formats that do not actually need the file contents, such as `DIFF_FORMAT_PATCH`: `run_diff()` would try to read the blob contents, but that blob might not have been written to Git's object database. This fixes https://github.com/git-for-windows/git/issues/2677 This patch _also_ fixes the expectations set by the regression test introduced in feea6946a5b (diff-files: treat "i-t-a" files as "not-in-index", 2020-06-20).
