patch 8.0.0394: tabs are not aligned when scrolling horizontally commit https://github.com/vim/vim/commit/abc39ab642791ae3d22a524516eeedb673a95d9d Author: Bram Moolenaar <Bram@vim.org> Date: Wed Mar 1 18:04:05 2017 +0100 patch 8.0.0394: tabs are not aligned when scrolling horizontally Problem: Tabs are not aligned when scrolling horizontally and a Tab doesn't fit. (Axel Bender) Solution: Handle a Tab as a not fitting character. (Christian Brabandt) Also fix that ":redraw" does not scroll horizontally to show the cursor. And fix the test that depended on the old behavior.
