Hi All,

It was brought to my attention that extracting an *empty* optional<> from a 
stream using the default provided operators (in optional_io.hpp), leaves one 
character behind, preventing any further extraction.

This is clearly a bug so I can only guess that no one is using it (except for 
the user that reported it).

The fix is quite trivial:

https://svn.boost.org/trac/boost/changeset/64206

And I've updated the test accordingly to make sure it works.

Can I marge the fix into the release branch?

TIA
