14451	RSS2 feed generates invalid category markup when 'default_feed' is 'atom'	benward	benward	"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.)"	defect (bug)	closed	normal	3.1	Feeds	3.0	normal	fixed	has-patch
