26520.2.patch​ removes the title attribute from wp_widget_rss_output() and makes $summary assignment more consistent with $date and $author.

Keep in mind that wp_widget_rss_output() is used on the frontend. We *could* outright remove it, but rather than making such a decision late in a release, let's start by using the wp_html_excerpt()'d version as the title attribute, too, and omitting the title attribute if the summary is being shown.

In 27691:

RSS widgets: Omit the title attribute when the summary is shown.

Trim the title attribute to ensure whitespace isn't rendered.
