secureAndSplit() assume that a given link with an initial colon is part of
the MAIN namespace. This might be false in some occasion, for example one might
want to create a link to a template:
{{:mytemplate}}
This will render as a link to [[mytemplate]] instead of [[template:mytemplate]].
I am coding a patch for this.
