* added functions added: - get_cursor_position() - set_terminal_title(title string) * implement term.get_cursor_position and term.set_terminal_title on unix * Cleanup * make x,y fields of term.Coord mutable * fix vrepl compilation * use more descriptive var names in term_test.v * do not change the current terminal title in dumb terminals; do not test term.set_terminal_title outside of CI * unix: in term.set_terminal_title, return true even for dumb terminals Co-authored-by: Brent Pryer <brent@pryermachine.com> Co-authored-by: Delyan Angelov <delian66@gmail.com>
