-If you have an actual diff (as opposed to a darcs patch created with 'darcs send'), then .diff is
-good, because Trac knows how to render them. At least it does on the attachements I looked at
-on #684 . I haven't checked to see what a darcs patch file attached with a .diff filename looks like,
-I think it could get pretty ugly.
-On the other hand, downloading the diff with "Download Original Format" gets a content-type which firefox
-insists upon saving instead of displaying. I think I'm ok with that.. what I care about is being able to
-review the change easily, and Trac's diff markup is pretty good.
