 If you override the 'default_feed' filter to return 'atom' (to make Atom
 format feeds the WordPress default at /feed/), the RSS2 format is broken
 because it does not explicitly declare 'rss2' as its category format,
 instead implying the default from `get_default_feed()` in
 `get_the_category_rss()`. When 'default_feed' is set to 'atom', Atom
 formatted categories are returned in RSS.

 Attached is a one line patch for feed-rss2.php, which explicitly declares
 the format when including categories.

 (Credit for this catch to my colleague Michael Lodick at Yahoo, whose feed
 importer I broke with the format religiosity that exposed this bug.)
