I've released difftastic 0.68! A smaller update, but still worth upgrading: * Improved Bash, C, Go, Lua, Nix, Perl, Python, Rust, Scala, Swift and YAML parsing. * Minor display and git compatibility fixes.

Cleaned up an old git repo of Ansible playbooks and it's amazing how much is just Docker now. Docker handles process supervision, centralises logging, and containers coexist without issues. It's nice when things get simpler.

It seems really odd to me that git uses 'cached' terminology for staging. For example, `git add somefile.rs; git diff --cached`. Caching implies state that you don't mind losing. There's very little state I want to lose in version control!
