Thank you very much. I'm the author of subvim (https://github.com/fatih/subvim) . And if this works fine I will promote this as the go-to editor to use subvim.
That would be grand. I've been using this for a few months now, and everything works OK - it was only this build that included Lua support (since I enabled it locally for myself a while back), but I've already tested the fixed binary on another Mac with no ill effects. Just grab a fresh DMG from the same place.
EDIT: fixed! Disabled Lua for now, I have both my own build and brew's installed, and it will take some time to sort out.
