As far as I know, you have to click the "Expand All" button to trigger
all of the content to be shown. I don't believe there is a shortcut link
for it. However, that seems reasonable to support, so you're welcome to
turn this into a bug/wishlist.

You can link to a single file's change like so:

http://bazaar.launchpad.net/~upstart-documenters/upstart-cookbook/trunk/revision/85/upstart_cookbook.rst

and you can get a complete raw diff for a revision, but there's no way of getting the whole diff for a revision in a single page. It would be a good feature, and probably pretty easy to add ?expanded=1 to the url and have that trigger a fetch of all the diffs. I changed away from generating the diff all in one page because of performance concerns, but maybe that's no longer relevant with bzr improvements (actually these days, I'd be tempted to do the pretty page by having the page's ajax the complete diff url and turn the diff into nice DOM diff view in pure js...)

You can get a diff by going to
.../diff/1234/12345

Its even linked in the 'compare this revision to another' UI, its only
not linked when looking at a single rev.
