Short summary: The parameters in Zend_View_Helper_Url are not url encoded when using the default parameters.

Long description: Today the parameters sent to Zend_View_Helper_Url are not url encoded so the programmer has to encode the parameters manually.

// route example:
// http://host/users/:user/*
// name of the route: "user"

$name = 'John Doe';

$parameters = array(
    'name' => urlencode($name) // url encode manually
);

echo $this->url($parameters, 'user'); // echo url

This works fine. But when I go to the generated url (http://host/users/John+Doe) and want to see his statistics, i need to add a new parameter "show" with value "statistics". New url: http://host/users/John+Doe/show/statistics.

So, standing on http://host/users/John+Doe i wouldn't have to re-send the name-parameter (John Doe) since the helper should use the current parameters as default.

$parameters = array(
    'show' => 'statistics'
);

echo $this->url($parameters); // generates: "http://host/users/John Doe/show/statistics" - problem is the current parameters (John Doe) is not url encoded this time (note the missing +).

Note that "John Doe" is not url encoded this time. The only workaround I've found is to always pick up the current parameters, url encode using urlencode() and re-send them all to the helper.
