I concur, and in fact, that reasoning (albeit with
different examples) _is_ why I asked, especially
about the removing and/or redefining --- some of
so-called `libc's I am(!) working with do not have
some of the % codes or, in one case, a broken one
(which I therefore want to avoid using).

yep. I first ran into this sort of checking with
the similar `lint' directive /*PRINTFLIKEn*/ where
<n> was the argument with the format string (the
args to print were, AFAICR, assumed to be n+1 ...).
I've been using this type of checking ever since
