patch 8.1.0706: tabline is not always redrawn commit https://github.com/vim/vim/commit/e12bab3144af8943937bd0ff4bc57f04e53037b3 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Jan 8 22:02:56 2019 +0100 patch 8.1.0706: tabline is not always redrawn Problem: Tabline is not always redrawn when something that is used in 'tabline' changes. Solution: Add ":redrawtabline" so that a plugin can at least cause the redraw when needed.
