patch 9.0.1785: wrong cursor position with 'showbreak' and lcs-eol
Problem: wrong cursor position with 'showbreak' and lcs-eol
Solution: Add size of 'showbreak' before when 'listchars' "eol" is used.
Also fix wrong cursor position with wrapping virtual text on
empty line and 'showbreak'.
closes: #12891
