Sorry.  I misread your email.  I thought that you were providing new
information.  I said that the entry from Red Hat did not overflow.  I
thought that you had tested the Red Hat linux case and were providing
your findings.  I was mistaken.  You just thought it necessary to hammer
your point home again.

I misread 1042 as 1024.  I guess I'm a touch dyslexic.

Too bad that your concern does not go as far as providing a patch.

As I mentioned, when I looked at the termcap entry, I did not see any
easy way to reduce it.  Since there are probably scores of programs
using this termcap entry, eliminating pieces from it is not something
that I would undertake lightly.  I could end up removing functionality
from programs which are relying on it.  These programs have already
apparently increased their buffer sizes.

Maybe we can stop talking about this now?  Or do you want to be outraged
some more?
