Description:
Using action=render on a page that links to a special page (e.g.
[[Special:Allpages]]) results in a weird link in the output (see URL): obviously
the link is parsed twice, as two html link-tags are visible.

Cause: this bug arises from the special treatment of links to Specialpages in
combination with the full links (incl $wgServerUrl) in the href-attribute.
Unlike normal links, those to special pages are not replaced by a linkholder but
inserted directly (via Skin::makeKnownLinkObj). With $action == 'render' links
are inserted with $wgServerUrl (which is useful). After this parsing of the
internal links the external links are parsed. The value in the href-attribute is
now considered as a free external link and replaced with a new link-tag of class
'external free'.

Solution: ?, perhaps the regex '/(\b(?:'.$wgUrlProtocols.'))/S' in
Parser:replaceExternalLinks could be adjusted?
