[Moin-user] linking to a URL in navi-bar broken?

[Rick Vanderveer]

It seems this broke between 1.7.0rc3 and 1.7.0 (final).  It was
working in all prior releases up to and including 1.7.0rc3.

In my tabs (navi-bar configuration in farmconfig.py), I have a link to
an external server. The code is:
        u'[http://mail.example.com Webmail]',

As of 1.7.0, it displays:
//mail.example.com Webmail]

Clicking on this tab takes me to the InterWiki page.  As far as I can
determine, it's trying to find an interwiki named "http:".  Am I
missing something?  Is there something I need to fix?
