Didn't detect new file correctly

[Mizuchi]

It looks like patchreview-vim didn't handle new files in diff correctly. Here is an example to reproduce this issue

[ytj@localhost ~]$ mkdir repo
[ytj@localhost ~]$ cd repo
[ytj@localhost repo]$ git init
Initialized empty Git repository in /home/ytj/repo/.git/
[ytj@localhost repo]$ echo whatever > a
[ytj@localhost repo]$ git add a
[ytj@localhost repo]$ git commit -m "first"
[master (root-commit) 2be937f] first
 1 file changed, 1 insertion(+)
 create mode 100644 a
[ytj@localhost repo]$ echo hello > README
[ytj@localhost repo]$ git add README
[ytj@localhost repo]$ git commit -m "add readme"
[master 8245157] add readme
 1 file changed, 1 insertion(+)
 create mode 100644 README
[ytj@localhost repo]$ git diff HEAD^
diff --git a/README b/README
new file mode 100644
index 0000000..ce01362
--- /dev/null
+++ b/README
@@ -0,0 +1 @@
+hello
[ytj@localhost repo]$ vim -c "DiffReview git diff HEAD^"

Basically it simply added a new file in the last commit. When I was "DiffReview git diff HEAD^" to review the diff for the last commit, I got such error:

Source directory: /home/ytj/repo
------------------
ERROR: Original file b/README does not exist.
New file        :  b/README
-----
Done.

It seems that I am not processing strip levels (e.g. 1 here for b/ prefix) for patches doing file additions or removals. I'll need to revisit my code to see why I did that before I relax that restriction. This might take a while as I am currently traveling. Meanwhile you can apply this patch and see if it doesn't break other things for you.

Your patch works for me. Thanks!

I have patched it locally the same, it works for me!
