patch 9.0.1813: linebreak incorrect drawn with breakindent

Commit: https://github.com/vim/vim/commit/1d3e0e8f3110a7807431eae056914ccea57b057b

    patch 9.0.1813: linebreak incorrect drawn with breakindent

    Problem: 'linebreak' is incorrectly drawn after 'breakindent'.
    Solution: Don't include 'breakindent' size when already after it.

    closes: #12937
    closes: #12940
