描述
Ref. #2358
Also known as Set Left and Right Margins. This feature is used by terminal applications like tmux and (neo)vim to optimize pane scrolling. Real xterm supports it, many not-real-xterms don't, so Neovim patches out this functionality for xterm pretenders (which it tries to detect via the XTERM_VERSION environment variable).
Right now, forcing Neovim to use the smglr results in this: https://asciinema.org/a/Qcgm1znQy3nE8DnCc0jnrjXMi (versus not using them).
