Category RSS feed function broken with URL rewrites

[gwagenknecht]

If you have URL rewrite enable the get_category_rss_link function in feed.php returns wrong feed URLs. It forgets to add a slash between the category link and the feed suffix. For example /category/mycategoryname becomes /category/mycategorynamefeed which is wrong.

The fix is quite simple. In feed.php change line 137​ from:

$link = $link . user_trailingslashit('feed', 'feed');

to:

$link = trailingslashit($link) . user_trailingslashit('feed', 'feed');

The fix isn't quite correct.

There are two of these issues in feed.php

In both cases a url should be built and then user_trailingslashit called.

e.g.

$link = user_trailingslashit($link . '/feed', 'feed');

Patch for trunk

Westi, but in that case, people who DO have trailing slashes will get:

http://example.com/category/foo//feed/

If we're adding something to the end of the URL, we must use trailingslashit() on the previous part. And then we use user_trailingslashit() on the last part. See patch.
