patch 9.0.1836: display wrong with virttext, linebreak and breakindent

Commit: https://github.com/vim/vim/commit/ce53e3ea55d12d222a73510d772e786b7ae29c8d

    patch 9.0.1836: display wrong with virttext, linebreak and breakindent

    Problem:  Wrong display with "above" virtual text and 'linebreak' or
              'breakindent' and 'showbreak'.
    Solution: Exclude size of "above" virtual text when calculating them.

    closes: #13000
