Discussion:
The default behavior of setbuf() is described only for the
situation that gptr() != 0 && gptr() != egptr():
namely to do nothing. What has to be done in other situations
is not described although there is actually only one reasonable
approach, namely to do nothing, too.
Since changing the buffer would almost certainly mess up most
buffer management of derived classes unless these classes do it
themselves, the default behavior of setbuf() should always be
to do nothing.
Proposed resolution:
Change 31.6.3.5.2 [streambuf.virt.buffer], paragraph 3, Default behavior, to: "Default behavior: Does nothing. Returns this."
