vim-patch:8.0.0380: with 'linebreak' double wide char wraps badly

Browse Source 
Problem:    With 'linebreak' set and 'breakat' includes ">" a double-wide
            character results in "<<" displayed.
Solution:   Check for the character not to be replaced. (Ozaki Kiichi,
            closes vim/vim#1456)
