Mail does not store an index into mail files, but reparses them each time it starts
up.  It does this by looking up "From" lines.  If it were to interpret a From line
which was inserted because of a forwarded message, say, as a valid mail header,
it would split the message apart.  Therefore the mailer puts a ">" character before
lines which start with "From" so they won't look like valid message beginnings.
