At present this 'I' flag doesn't seem to be documented at all in the libc
manual.  Perhaps you could document exactly what it's meant to do and
where it can go?  In GCC I've implemented the format checking for it as a
flag for decimal integer printf formats - though the glibc format code
looks like it handles this flag after width and precision as well as where
normal flags are accepted.
