He did say "sane".

Good internationalisation requires you know where the messages are and
where the substitutions (%foo) are. So the entire operation would in fact
require

1.	An option to set "translation friendly please"

2.	A tiny modification to the snprintfoo code to support putting
some kind of marker before/after arguments and maybe doubling a symbol to
avoid vagueness

The submission is overkill compared to what is required for translation
tools and syslog.
