If a paramater contains an equal sign, it is swallowed.
enter into a page {{template sandbox|x=y}}
or go to http://en.wikipedia.org/wiki/User:AndreasJS/equalsigntest
Expected behaviour: the page should show 
<b>First</b><br>
    x=y
Observed behaviour: the page shows 
<b>First</b><br>
   {{{1}}}
This is annoying because many urls contain equal signs: it is impossible to use the teplate //en.wikipedia.org/wiki/Template:copyvio with an url 
containing an equal sign, such as one pointing to a php.
