patch 8.0.0996: Mac: t_RS is echoed on the screne in Terminal.app commit https://github.com/vim/vim/commit/833e0e3c8ccd6047dd596c4ffd68cb0ab13b4e41 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Aug 26 15:16:03 2017 +0200 patch 8.0.0996: Mac: t_RS is echoed on the screne in Terminal.app Problem: Mac: t_RS is echoed on the screne in Terminal.app. Even though $TERM is set to "xterm-256colors" it cannot handle this xterm escape sequence. Solution: Recognize Terminal.app from the termresponse and skip sending t_RS if it looks like Terminal.app.
