Published a draft post use post.php instead of post-new.php

I find that this problem is also noted in the use of the Bookmarklet link shown on the write post page.

Let me explain the scenario in details.

1. Write Post

2. Click <Save and Continue Editing> more than once.

3. Click <Publish>

4. Then it will direct to a page with only WordPress logo, Documentation and Support Forum hyperlink.

This is exactly what happens when you use the bookmarklet link.

1. Click on bookmarklet link in any page.

2. It will direct to a page with only WordPress logo, Documentation and Support Forum hyperlink, instead of to the write page.
