No flexibility in comments RSS feed

[mdawaffe]

wp-commentsrss2.php does not give any flexibility in determining what sorts of comments should be displayed. All we get is the feed for individual posts/pages or for the whole site. Additionally, no filtration is allowed.

The attached hangs on the coat tails of WP_Query. Comment feeds for time, category, search, post, page, and the main site should all work. Filtration on JOIN and WHERE is allowed.

I've not done any benchmarking comparing this patch vs. the old system.

Oops. Here's how to access the comment feeds supplied by this patch:

Working on refreshing old patch.

[rob1n]

Adds have_comment(), the_comment and a bunch of WP_Query stuff, including the original patch. *needs testing*

2485.3.diff

1. All of rob1n's 2485.2.diff (rob1n: please verify)
2. Get rid of some parse errors.
3. Get rid of have_posts() (I don't think it's necessary) and use have_comments().
4. Somewhat better comments feed titles.

[rob1n]

Looks good. I think this is ready for commit?
