[wp-hackers] Post title in comments feed in 1.5.2

[Michael D Adams]

Or... I could think about what I'm saying/actually try things out  
before writing stuff.  Whichever people'd prefer.

It seems all of the posts involved in the comments feed get cached  
via WP_Query.  I'm not sure if any of these joins are necessary.

I'll let someone else come along and say something actually  
intelligent now :)
