Electric spacing 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 electric-spacing-mode' to toggle this minor mode.

reimplementing as a minor mode and providing an initial patch for
that.
