 - Searching for the pattern `//` with regular expression search is now interpreted literally and will search for `//`. Previously, the `//` pattern was interpreted as our regular expression syntax `/<regexp>/` which would in turn be intrpreted as the empty string. Since searching for an empty string offers little practically utility, we now instead interpret `//` to search for its literal meaning in regular expression search.
