patch 9.0.0745: wrong cursor position when using "gj" and "gk" in a long line

Browse Source 
Problem:    Wrong cursor position when using "gj" and "gk" in a long line.
Solution:   Adjust computations for the cursor position and skipcol. Re-enable
            tests that pass now, disable failing breakindent test.
