Reports a given indent violation and properly pluralizes the message
@param {ASTNode} node Node violating the indent rule
@param {int} needed Expected indentation character count
@param {int} gotten Indentation character count in the actual node/code
@param {Object=} loc Error line and column location
@param {boolean} isLastNodeCheck Is the error for last node check
@returns {void}
