Description:
When approved URLS are added to the page by clicking on the (approve links) link, I observe the following

• If a url is referred to twice it is added twice, eg [(approve links) edit diff], [(approve links) edit diff]
• Case causes the URL to be added twice, eg http://pmwiki.org, http://PmWiki.org

Would it be possible to have

• URLs only added once
• case to be ignored for URL

Gratuitous enhancement request:
Rather than having links added at the bottom of the page would it be possible to have URLs sorted (eg strip off http:// and www. if present)

Crisses: While fixing this, note an additional issue: If the URL is stored in a PTV such as (:url:http//:example.com:) the final : is grabbed. The URL is still listed as needing approval. adding a final / fixes the issue i.e. (:url:http//:example.com/:) but some people won't do that.
