I tried running this on a Mac but got an error. Assumed it was because of some sed version difference. Perhaps the code on Github is just broken.

That's probably because you used BSD sed. Running it on my BSD sed also gives an error, presumably because it thinks the `}` is a part of the label in `binput}`.
However it works fine in GNU sed, and now that you mention it, GNU sed's extensions were not used, like the `-z` flag to slurp all input in one "line" to avoid `:input;$!{N;binput}`.
