If a page that has attachments is deleted, before confirming, we'll se a message saying:

There are 1 incoming link(s) to this page. These links will be broken when this page is deleted

Feature Request:
Can Jira's behaviour be changed to prevent broken images (links) on dependent pages?

Steps to Reproduce:

1. create a new page with an image
2. on edit mode, copy the content
3. create a new page using the content from the previous page
4. click Tools-> Delete on the 1st page (you'll see the dialog box saying there is 1 incoming link)
5. confirm deletion
6. check 2nd page. (has a "Unknown Attachment")
