I tried replace Vec with SmallVec in a really hot loop in difftastic, and it's a huge speedup. It almost *halved* the runtime of one of my test files!
I've done a lot of performance tuning of difftastic, so it's surprising to see such a big win.

(1) A local copy of the manual doesn't have the version (OpenBSD packaging fixes this).
(2) One of my dependencies has been yanked (Void Linux packaging fixes this).
