Maybe you should add NEWS. |

This change doesn't impact end users. I don't think that a NEWS entry is needed. |

Can you put the break here? Something like:

OK!
One line is 85 characters now, but I think it's most readable this way.

This switches sprintf format strings in unicode_fromformat_arg to compile-time literals, avoiding
-Wformat-nonliteralwarnings and maybe even allowing optimizing thesprintfcalls.The macros aren't too readable so I'm generous with comments.
(Another option would be code generation, see the first commit.)
