At this point I'm sure that everyone really couldn't care less,
and I didn't heed my own warning to just get some sleep...so of course
I've got another patch for freopen() that is perhaps a little more
reasonable than the first, so that if you're doing something strange
and had opened the stream with funopen() you don't loose.
