Subject: git diff --word-diff problem
Message-ID: <4F0EA23D.3010603@yandex-team.ru>

Hello.
I've got a couple of generated files with obfuscated code.
I want to word-diff them just to make sure that everything is right.

The thing is when word-diff gets oneline file without newline at the end 
it compares it with regular line by line diff.

Here is an example. Two one line files generated with perl -e "print 'a 
'x10" > file

git diff --word-diff=plain file1 file2
diff --git a/file1 b/file2
index 3526254..0515a63 100644
--- a/file1
+++ b/file2
@@ -1 +1 @@
[- a a a a a a a a a a-]
  No newline at end of file
  {+a a a a a ab a a a a+}

Git shows that the whole line is different.
And if I add newlines to that files everything works just as expected

git diff --word-diff=plain file1 file2
diff --git a/file1 b/file2
index 1756d83..1ec45b9 100644
--- a/file1
+++ b/file2
@@ -1,2 +1,2 @@
  a a a a a [-a -]{+ab +}a a a a

Is that a bug or I've missed explanation in docs?
