Yeah, when the tech on my ISP posted this I emailed him directly
rather than posting to the newsgroup so as not to embarrass him.
We've probably all heard 'irretrievably corrupted' many times
over the years; it's common knowledge.
But it works. I've done it and it never fails if this is the
cause of the corruption. As he patiently explained to me, it
works because any legal cr/lf's are converted to cr/cr/lf and you
convert them back to cr/lf. If you were doing this recursively,
that would be a problem.
Best,
Rick
