We shouldn't need this anymore. See below.
We already have a list of diffsets. Rather than do this and the above (which will just add more SQL complexity), we should use the 'diffsets' variable. Instead of a query, we should just loop through the diffsets (or loop through once above and build a map we can use) to get this value.
Added "Show changes" links to interdiffs in changedesc blobs.
Review Request #3225 — Created July 18, 2012 and submitted
Added "Show changes" links to interdiffs in changedesc blobs. When a user uploads a diff, we show a link to the uploaded diff revision. We should also provide a linke to the interdiff, since that's what a lot of people will want to see. This is based on Curtis miller's change http://reviews.reviewboard.org/r/2810/ I've updated it to fix the remaining issues, and tweaked the text a little bit ("Show changes" instead of "Show changes").
Published a few versions of a diff and verified that the new link showed what I expected to.
