Support to ignore a block

Considering the following example:

```html

My paragraph with a link (

see here

).

The extra whitespace between the closing of the anchor and the parenthesis are an issue for us, it's creating an extra space, when viewed as HTML. Could there be an option, maybe a comment, that would disable the formatting for a specific block?

Out of scope? I let you be the judge.

I can also do a PR if you're interested.

首先检查 HTML formatter 如何处理嵌套元素周围的空白，以及它是否已经识别注释或配置选项。定义忽略标记或选项应如何限定一个块的作用范围，然后验证示例在不改变其他位置格式的情况下保留预期的空白。
