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