+Subject: [PATCH 03/45] Fix bug in strinfo
+
+We can't search for a larger needle inside of a smaller haystack, and
+unsigned integer subtraction tends to result in very large numbers
+rather than small ones.
+
+Add a check for this case and abort out immediately.
+
+Also add a test case (lifted directly from the docs) that demonstrates
+the problem.
+
+Issue discovered and tracked down by Milan Bouchet-Valat
