  POSIX uses 'restrict' in *wprintf() (see [v]fwprintf(3p)).
Let's use it here too.

Hi Michael,

I found this last one, which I didn't find through the glibc sources
because they have a bit of a mess with *printf() functions.
I checked that POSIX requires 'restrict'.

At this point, I still have a few patches about prototypes (not restrict),
but I'll buffer them for now.

Cheers,

Alex
