$ printf 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx12345x\n' | GREP_COLORS='sl=01;41:ne' grep --color=always 1234 (on some terms you need to repeat this more times until the term vertically scrolls to see the difference w/wo 'ne'). >From the discussion in the original report it seems, the reported xterm autowrap behaviour is DEC VT100 feature (for me historical bug that became feature) and could be deduced from the xenl terminfo capability. But as e.g. libvte interprets this different way, there is probably no simple fix (even in case grep would read terminfo). Maybe the xterm upstream will come with some idea Jaroslav
