function-calc-no-unspaced-operator

Disallow an unspaced operator within calc functions.

a { top: calc(1px + 2px); }
/**               ↑
 * The space around this operator */

This rule checks that there is a single whitespace or a newline plus indentation before the + or - operator, and a single whitespace or a newline after that operator.

The fix option can automatically fix all of the problems reported by this rule.
