    I'm not 100% sure either
    (in the context of curses that is - this is one of those features that
    is probably explained only in the SVr4 curses source code).

    But vt220's implement something that sounds like that,
    which guards text against erasure. I have a screen
    in vttest which demonstrates it.

    Perhaps it's missing the sgr string - I seem to recall noticing some variant of
    the rxvt terminfo (probably based on a termcap file) which lacked the sgr
    string.

    I have a notion that rxvt users tend to use slang, which apparently doesn't do
    anything with sgr - those users would not notice.
