For years I unknowingly used some, shall we say, deviant distribution of vim that would stay at the location of the highlighted search result after hitting `<Esc>` in the middle of a search instead of jumping back to the original position.

I've tried for more than a year now to forget that muscle memory, but I cannot for the life of me stop pressing `<Esc>` once what I've typed in the search has taken me to the position I'm searching for. 

Does anyone know a) how I can get that behavior back, b) what \*nix distribution had a copy of vim that defaulted to this behavior?
