Maybe someone can answer this for me...

Why doesn't isatty() clear errno before it returns?  It is determining
something by purposely trying to generate an error.  Seems reasonable
that it should then clean up after itself if it actually generated an
error.

Think of all the code that would stop behaving semi-irrationally if
this "fix" were installed.
