-/-- These tests are for the Perl >= 5.10 features that PCRE supports. --/
+/-- These are a few representative patterns whose lengths and offsets are to be 
+shown when the link size is 2. This is just a doublecheck test to ensure the 
+sizes don't go horribly wrong when something is changed. The pattern contents 
+are all themselves checked in other tests. Unicode, including property support, 
+is required for these tests. --/
