Make the vendored synth plain ASCII

Browse Source 
soundThing's comments use em dashes and an arrow, and this repository is
plain ASCII throughout because the tooling around it does not do Unicode.
Tests/docs.sh caught it the first time it ran against the new file, which
is what that check is for.

Comments only; nothing the compiler sees has changed.
