static VALUE
readline_s_get_line_buffer(VALUE self)
{
    if (rl_line_buffer == NULL)
        return Qnil;
    return rb_locale_str_new_cstr(rl_line_buffer);
}

Returns the full line that is being edited. This is useful from within the complete_proc for determining the context of the completion request.

The length of Readline.line_buffer and GNU Readline’s rl_end are same.

Raises NotImplementedError if the using readline library does not support.
