Fine, that's what CDL items are for. It seems odd, though, that diag_printf
would make such checks, while printf doesn't. Furthermore, it seems less odd
that it would make such a check on an argument string substituted for %s,
than on the format string itself, the latter almost always being a literal
string passed directly to the function by the caller.

Anyway, I don't have a dog in this fight. I was just musing that a CDL
option to take out the checking seemed more sensible than a CDL option to
add yet another check to it.
