[boost] Minor problem with i/o state savers documentation.

Regarding the i/o state savers for advanced standard attributes, the
documentation says that the destructor 'changes the stream's attribute back
to the saved value.' In the case of basic_ios_iostate_saver,  however, it is
not always possible to restore the stream state: a stream which was
originally 'good' may later have had its buffer set to 0, and such a stream
can never be 'good'.

I think it would be more accurate to say that the destructor in this case
'attempts to restore' the original value. Maybe a footnote would be
appropriate.
