Comment:

 I just attached a patch.

 It adds the member function get_option_name() to the exceptions:
 unknown_option, multiple_values, multiple_occurrences and validation_error

 The option name is set when exception is thrown, this gives the
 possibility for an appropriate error reporting when catching these
 exceptions.

 I also added a new test case program_options/test/exception_test.cpp which
 checks some exceptions. This test is not fully complete but a good place
 to add checks related to exceptions.

 Please comment.
