mutt, edit and Lines: vs me

Hi all,

this is not really a mutt-_ng_ question, but I'm sure someone here can
enlighten me.

I use a procmail recipe, that will add the number of lines of an email
to the header. So an email has lots of Received: lines, From:, To:,
Subject, etc. then some X-Spam-Foo and finally Lines: 51

My mails are saved as Maildir format and whenever I press 'e' to edit a
message, mutt will mark the message as deleted and construct a new
message (which is missing the Lines header!) and will then open this
mail in $EDITOR.

Two questions arise:
1. Why is it dropping the Lines header? (Ok, after editing, it might be
wrong, but sometimes I just want to take a look at the emails in vim)

2. Why does it even rewrite the mail to a new file?
