Docs: show console call with no-restricted-syntax (fixes eslint#7806)

 If you're using Node.js, however, `console` is used to output information to the user and so is not strictly used for debugging purposes. If you are developing for Node.js then you most likely do not want this rule enabled.
 
+Another case where you might not use this rule is if you want to enforce console calls and not console overwrites. For example:
+
+```js
+console.error = function (message) {
+  throw new Error(message);
+};
+``` 
+
+With the `no-console` rule, this will receive a warning/error. For the above example, you can disable the rule:
+
+```js
+// eslint-disable-next-line no-console
+console.error = function (message) {
+  throw new Error(message);
+};
+
+// or
+
+console.error = function (message) {  // eslint-disable-line no-console
+  throw new Error(message);
+};
+```
+
+However, you might not want to manually add `eslint-disable-next-line` or `eslint-disable-line`. You can achieve the effect of only receiving errors for console calls with the `no-restricted-syntax` rule:
+
+```json
+{
+    "rules": {
+        "no-restricted-syntax": [
+            "error",
+            {
+                "selector": "CallExpression[callee.object.name='console'][callee.property.name=/^(log|warn|error|info|trace)$/]",
+                "message": "Unexpected property on console object was called"
+            }
+        ]
+    }
+}
+```
+
