"No newline at end of file" can be non-trailing

[romamik]

Here is an example patch that fails to parse:

--- a/test.txt
+++ b/test.txt
@@ -1,4 +1,5 @@
 python
 eggy
 hamster
-guido
\ No newline at end of file
+
+hello
\ No newline at end of file

From my understanding, this indicator is added after the line if the line is last and has no \n character at the end.

Now this indicator is modeled as a boolean flag in the patch, but actually there should be two such flags, as we have two last lines: one before the patch and one after the patch.
