I actually prefer the first suggestion of just having a file-global bool.

If and when we get other checks that need to be done selectively [e.g.
"snprintf into a too short buffer produces a prefix of the full string",
which also came up during this discussion but was ultimately kept]
depending on the %<whatever> being exercised, we can add a "u32 nocheck"
with a bunch of bits saying what to elide.

Not insisting either way, just my $0.02.
