test files have a similar include layout to that of a .cc file. That is, include
session_utils.h first, newline, then non-system includes.

Done.

When you change FilteredEntries to not take a TabRestoreService then you won't
need this class. Instead you'll be able to pass in the entries directly. This is
one of the reasons I didn't want the function taking a TabRestoreService.

[noyau (Ping after 24h), 2011/09/20 17:09:35]

Done.

+          GURL(string16(ASCIIToUTF16(url))), string16(ASCIIToUTF16(title))));
+      current_navigation_index = 0;
+    }

+  };
+
+  TabRestoreServiceMock() : TabRestoreService(NULL) {
