yes - I implemented left/right margins in xterm in 2012 (patch #279) (not quite as long ago as repeat_char). however, the left/right margin feature was present earlier: REV:1.730 terminfo.src 2019/05/18 18:58:45 tom add vt420 left/right margins for xterm-new +# Left/right margins are supported in xterm since patch #279 (2012/05/10) +vt420+lrmm|VT420 left/right margins, + mgc=\E[?69l, smglr=\E[?69h\E[%i%p1%d;%p2%ds, > The neovim developers have pushed a workaround: > > https://github.com/neovim/neovim/issues/16238 ...which seems enough to fix their issue (they're checking if $XTERM_VERSION is set) Since the feature was already present in a different form, it seems that neovim is the only widespread user of this. My recent update simply gave neovim a different way to exercise it.

I don't see that it's necessary. By the way, #933053 is kind of stale - likely there's no sufficiently old systems with broken vte libraries to appease. -- Thomas E.
