Horizontal rule support

[gkumar-asapp]

Feature Request

Insert a horizontal rule by using three or more hyphens (-), asterisks (*), or underscores (_) on a line that is surrounded by empty lines. Each of the characters is the same for a horizontal rule. Whitespace between the characters is ignored.

---… | ***… | ___…
---… | ***… | ___…

This should look like as shown below.

/*:
This text is above the horizontal rule.

---

And this is below.
*/

Currently it is not showing any horizontal line.
