updated for version 7.3.597
Problem:    'clipboard' "autoselect" only applies to the * register. (Sergey
            Vakulenko)
Solution:   Make 'autoselect' work for the + register. (Christian Brabant)
            Add the "autoselectplus" option in 'clipboard' and the "P" flag in
            'guioptions'.
