forum thread-search feature

[bitwise]

I was going to explain it, but a picture is worth a thousand 
words. I also added some words for good measure.

I often arrive to a conversation that's 10+ pages long and wonder 
if I should comment on something mentioned in the original post. 
I would like to be able to figure that out without reading all 10 
pages, which I think is reasonable since not all problems related 
to something like a DIP would necessarily be related to each 
other.

I wouldn't know where to start on dlang.org, but I've implemented 
the same thing on another website in a matter of hours (a 
significantly less sophisticated site).

In hindsight, maybe I should have thrown this up on the 
appropriate Bugzilla as a feature request.
