Problem in 27_io/istream_sentry.cc (patch included)

If the function test2() of 27_io/istream_sentry.cc is run on a system that
exposes the behaviour described in libstdc++/944, the while loop never
terminates if eof is not processed correctly. I believe it is the
correct handling of eof that the function test2() is checking. Therefore an
explicit exit of the loop for a misbehaving implementation should be
provided. I apologise if this is a bogus report.
Thanks very much for fixing the problem described in libstdc++/944.
Peter Schmid
