           Summary: [webkitpy] Make diff_text generate correct diff if
                    there is no newline at the end of file
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tmeszaros.u-szeged at partner.samsung.com


If only one line break is the difference between the actual and expected result, the pretty diff will fail.

Example:

actual result:
 "A\n\nB"

expected result:
"A\n\nB\n\n\n"

current diff:
"--- exp.txt
+++ act.txt
@@ -1,3 +1,5 @@
 A

-B+B
+
+"

expected diff:
"--- exp.txt
+++ act.txt
@@ -1,3 +1,5 @@
 A

-B
\ No newline at end of file
+B
+
+"
