function names.

Problem: 'linebreak' may lead to wrong Visual block highlighting when
end char occupies multiple cells (after 7.4.467).
Solution: Exclude 'linebreak' from the ending column instead of setting
'virtualedit' temporarily (zeertzjq).

Bug doesn't apply to Nvim.
Problem: Wrong display with wrapping virtual text or unprintable chars,
'showbreak' and 'smoothscroll'.
Solution: Don't skip cells taken by 'showbreak' in screen lines before
"w_skipcol". Combined "n_skip" and "skip_cells".
closes: vim/vim#12597b557f48982
Problem: "<<<" shows for 'smoothscroll' even when 'showbreak is set.
Solution: When 'showbreak' is set do not display "<<<".
