+Patch 7.4.074
+Problem:    When undo'ing all changes and creating a new change the undo
+            structure is incorrect. (Christian Brabandt)
+Solution:   When deleting the branch starting at the old header, delete the
+            whole branch, not just the first entry.

+LETTERS TO THE EDITOR (The Times of London)
+
+Dear Sir,
+
+I am firmly opposed to the spread of microchips either to the home or
+to the office.  We have more than enough of them foisted upon us in
+public places.  They are a disgusting Americanism, and can only result
+in the farmers being forced to grow smaller potatoes, which in turn
+will cause massive unemployment in the already severely depressed
+agricultural industry.
+
+Yours faithfully,
+        Capt. Quinton D'Arcy, J. P.
+        Sevenoaks
