This is so one doesn't have to wonder if the ;; target is north or south in the buffer. ;; ;; The philosophy is that `wrap-search' mostly shouldn't be ;; used for searching - that is possible as well, of course, ;; using the same command - rather, it is used to quickly ;; navigate a buffer. ;; ;; To use the package without keyboard shortcuts isn't ;; recommended.
