Source_url is wrongly used in aggregator_feed_source preprocess function

Hi all,
I've noticed a functional bug in aggregator module where on the aggregator-feed-source.tpl $source_url gets printed but in its preprocess function the variable comes from $feed->link, not the ->url where it should.
I'm not fully sure is it the only place where aggregator prints wrong value out, but for sure it is.
Test case:
Enable aggregator module.
Create a new feed under admin/config/services/aggregator/add/feed and add a valid rss url to its URL field.
Save the feed and visit its source page, clicking on the name of the created feed on admin/config/services/aggregator page.
You'll see your site's URL instead of the previously set url on the feed's page (if this feed is the first and only created one on your site, it should be available under aggregator/sources/1)
Semantically this URL should show the url of the feed, not the site's one or any others, also when you go to configure the feed (aggregator/sources/1/configure) you see the URL of the feed in the textfield of URL.
Patch is coming.
