Un-escaping "From " is a very risky business; different mailers
escape it in different ways, and ">From " at the start of a line
does not always mean that the line is in fact "From ". Basic rule:
don't try it. There's some fairly good material on the Netscape site
on this; I don't have the URL handy, but searching for "bsd mailbox"
on that site should do the trick.
