vim-patch:8.1.0706: introduce :redrawtabline #10570 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. https://github.com/vim/vim/commit/e12bab3144af8943937bd0ff4bc57f04e53037b3

func TablineWithCaughtError()
vim-patch:7.4.1723 Problem: When using try/catch in 'tabline' it is still considered an error and the tabline will be disabled. Solution: Check did_emsg instead of called_emsg. (haya14busa, closes #746) https://github.com/vim/vim/commit/f73d3bc253fa79ad220f52f04b93e782e95a9d43
