Not a full link, why would it "work"?

REOPENing the bug. Sorry for earlier misspellings!

At bug 4282 comment 13 are the following links:
a) fails [[wikinews:sr:Корисник:Gangleri]]
b) fails [[commons:User:Gangleri/tests#wikinews:sr:Корисник:Gangleri]]

At bug 4247 comment 8 are the following links:
c) works [[s:it:template:wikivar]]
d) works [[wikisource:it:template:wikivar]]

MediaZilla does not have a preview. Adding some tests here:

a1b) fails [[wikinews:sr:Категорија:User_sr]]
b1b) fails [[commons:Commons:Village_pump]]

interwiki prefix "wikinews:" - main namespace
a2c) fails [[wikinews:sr:Главна_страна]]
a2d) fails [[wikinews:sr:Main_Page]] (redirect latin characters)

interwiki prefix "commons:" - main namespace
b2c) fails [[commons:Village_pump]]

interwiki prefix "wikinews:" - generic namespace
a3a) fails [[wikinews:sr:user:Gangleri]]
a3b) fails [[wikinews:sr:category:User_sr]]

interwiki prefix "n:"
a4a) works [[n:sr:Корисник:Gangleri]]
a4b) works [[n:sr:Категорија:User_sr]]
a4c) works [[n:sr:Главна_страна]] (main namespace)
a4d) works [[n:sr:Main_Page]] (main namespace / redirect latin characters)

interwiki prefix "n:" - generic namespaces
a5a) works [[n:sr:user:Gangleri]]
a5b) works [[n:sr:category:User_sr]]

Please change "Product" and "Component" if necessary (if this is a MediaWiki bug).

best regards reinhardt [[user:gangleri]]

Doesn't seem to have anything to do with bugzilla; it passes the links through to
en.wikipedia.org as expected. Not all interwikis are forwarded from there.

Thanks Brion! It would be nice that wiki links to commons: should not generate
the bad titles ad [[en:]]. They are used quite often here (at MediaZilla).
