Re: fflush & close behavior not well-defined

[Andrew J. Schorr]

I'm inclined to agree, although I'd point out that the potential "change" to
gawk would not break any existing programs, but merely extend the capability in
case someone needs it. But it's probably not worth the effort. Nonetheless, it
might be worth documenting somewhere that AWK behavior is not well-defined in
this respect.

Regards,
Andy
