Items expire after 16 weeks, no 'do not expire' option.

Hi, I'm using the core aggregator to display my RSS feeds, but recently some stopped showing up.

I believe the problem is that the feeds are older than 16 weeks, and drupal only has an option to show feeds up to 16 weeks old.

These feeds I require still on my site, and they are much older than 16 weeks, and not getting any younger (like us all).

Can we have a 'do not expire' feeds option please?
