    PR libstdc++/59427
    * include/bits/fstream.tcc (basic_filebuf<>::overflow,
    basic_filebuf<>::xsputn): Per lwg/596, ios_base::app implies
    ios_base:out.
    * include/std/fstream (basic_filebuf<>::_M_set_buffer): Likewise.
    * testsuite/27_io/basic_filebuf/sputc/char/59427.cc: New.
    * testsuite/27_io/basic_filebuf/sputn/char/59427.cc: Likewise.
