make atom feed signal something when the summary is cut off by <!--more-->

[leoboiko]

When the post doesn't contain a <!--more--> cutoff, or if the cut is beyond the automatic summary size (55 words), Wordpress will add the string '[...]' to the Atom summary. This makes it easy for people watching the feeds to know that there's more content to be seen in the full post.

But, when the cut is *before* 55 words (which is often the case), WP simply ends the summary abruptly, without the "more" link ('cause summaries are text-only) nor any other kind of indication. Attached patch is an attempt to make it add '[...]' in these cases, too.

Please review it as I'm not comfortable with WP internals. It seems to work :)

Fixes are first considered on trunk. Can you consider the behavior in trunk (2.5) and if still a problem there provide a patch.

Maintenance releases only get fixes for severe issues.

I didn't actually install from svn to test, but I did checkout the source and it seemed to be the same. I'll try it for real later.

This shouldn't be an issue anymore since we don't cut off at more anymore.
