I'm not sure I really understand the problem but I think this would be a step backward. There are facilities to manipulate these sequences. E.g. see what no_terminal_escape_file or escape_buffering_file do. One option might be to reimplement this as a ui_file that will only split at un-styled spaces; and if the screen isn't big enough just omit the box. Then print_gdb_hints wouldn't need two branches printing the same stuff. thanks, Tom
