* libio/Makefile (tests): Add tst_wprintf2.
(tst_wprintf2-ARGS): Define.
* libio/tst_wprintf2.c: New file.
Based on a test case by Yoshito Kawada <KAWADA@jp.ibm.com>.
* libio/wfiledoalloc.c: Only allocate external buffer if this
hasn't happened yet.
* libio/wfileops.c (_IO_wdo_write): Overflow only if there is really
something in the buffer. gconv call can write up to end of the
buffer, not only _IO_write_end.
(_IO_wfile_overflow): Allocate also external buffer.
* stdio-common/vfprintf.c (process_string_arg): Handle multibyte
strings with precision in vfwprintf correctly.
* stdio-common/vfprintf.c: Fix completely broken handling of
unbuffered wide character streams.
