[BUG] wprintf(L"%s", str) expects str to be wide

[Craig Howland]

Corinna:
      Are we looking at the same place?  Lines 1200-1217 of 
libc/stdio/vfwprintf.c version 1.10 are what I looked at.  I only see wide 
functions there.  I'll quote from line 1199 to get the #endif:
#endif /* _MB_CAPABLE */
                         if (prec >= 0) {
                                 /*
                                  * can't use wcslen; can only look for the
                                  * NUL in the first `prec' characters, and
                                  * strlen () will go further.
                                  */
                                 wchar_t *p = wmemchr (cp, L'\0', prec);

                                 if (p != NULL) {
                                         size = p - cp;
                                         if (size > prec)
                                                 size = prec;
                                 } else
                                         size = prec;
                         } else
                                 size = wcslen (cp);

                         break;
