It is just an innocent hyphen not a hyphenator

Writer, please stop harassing me

This debug code was behind > 1 before
9ace8bebd88ff41d65eeaa87a6d1f1dfd8875b6d, so it probably was broken for
ages (or even forever), and all it does now is obscure my terminal with
hundreds of useless messages whenever I open an RTL document since
basically any weak LTR run next to RTL one will have the same script
type, but this code warns about it without explaining what one should
fix here.

I got fed up, whoever knows what to fix here, please do, but for now I’m
just hiding it.
