zstyle is awesome but a little verbose to type in every time.
Not sure why I added this; appears to be unneeded now.
Thanks to Quentin via Disquss for the tip.
Rather than add a bunch of platform-specific tweaks and changes to my dotfiles I'm trying out using wrapper scripts instead. This OSX + tmux clipboard fiasco is a giant PITA too. WTF, Apple? Why oh why didn't I just request a Lenovo?
ssh has this builtin. Woot.
