PRs are good in any case, both to provide a record of what happens, and
to make certain we don't forget to fix anything.

There is no quick fix that I can think of.  The problem is in the 'if'
conditions being tested in the std::basic_filebuf::setbuf() function,
in bits/fstream.tcc, line 460-ish.  We want to take the first branch,
instead we take neither branch.  The call to is_open should be replaced.

There is no has_this_buffer_done_any_IO_yet function, but if there were,
that's what should be called instead.  I haven't looked any further.

If you file the PR, you get the added bonus of being instantly notified
as soon as it's fixed.  :-)
