Aggregator block: Display the more link only if there are items present

+1 generally on the patch, but:

1) $read_more is not initialized and will create a Notice error when there is no more feeds to read.
2) cvs has this bug, too, and should be fixed first so that we are sure we won't forget to include the fix in the next version :)
3) diff from the root: http://drupal.org/patch

Rolled a patch before I saw this issue, so you're not the only one considering this a minor bug.

Here's a patch against 5-dev.

$type will be either feed or category, so $read_more will be defined (as will $result). Text change is for another patch.

Code comment may be obvious.

A side effect of having an empty block content is that such blocks will disappear from the layout.

This is a behavioral change, but one that I believe is more in line with the way the rest of Drupal works (i.e. if it isn't relevant, it isn't shown.)

All that being said, patch in #4 looks OK to me, works as advertised, and doesn't break anything. RTBC.

COmmitted to HEAD.

apparently, I already applied this some tme ago.
