Smart Operator mode is a minor mode which automatically inserts surrounding spaces around operator symbols. For example, `=' becomes ` = ', `+=' becomes ` += '. This is most handy for writing C-style source code. Type `M-x smart-operator-mode' to toggle this minor mode. Acknowledgements Nikolaj Schumacher <firstname.lastname@example.org>, for suggesting reimplementing as a minor mode and providing an initial patch for that.
