feeds aren't canonical

[bubel]

Pretty permalink feeds aren't canonical.

ENV: WP trunk r8190 (2.6-beta1)
Browser: Firefox/3.0

The canonical URL for the feeds - both posts and comments - is not
working as intended. The following error only occurs with 'pretty'
permalinks enabled. My specific testing involved the "Day and name"
option.

The issue is evident when pointing your browser to "​http://www.example.com/feed". The expected outcome is for the browser to display, upon load, the canonical URL, or
"​http://www.example.com/feed/" Instead, the address bar will remain
populated with the address that you entered (i.e. no "/" added).

The issue is only evident with the feed URLs. For instance, pointing
your browser to "​http://www.example.com/page" will yield the correct
outcome, and redirect to "​http://www.example.com/page/". The same goes for categories, posts, etc.

TODO: make sure that a high percentage of feed readers follow 301 redirects.

If they don't, would not exit()'ing after sending the 301 solve the problem? That way the feed content is still there for readers that don't know what to do with the 301.

Feedburner uses 301 redirects in their plugin.

301 is the recommended way to migrate feeds to new URLs.

Possibly a duplicate of #4604

Marking as fixed - seems to work great. Let's start new tickets for any bugs.
