[erlang-questions] io:format validation

Where in the OTP source is the validation of format strings done?
Specifically, when you have io:format/2,3 or io_lib:format/2,3 in your code
and the compiler complains about the number of patterns not matching the
number of arguments.

I'd like to use this elsewhere, for instance, where a library call
eventually calls io_lib:format/2,3 but the caller into the library is not
validated.
