[Exim] extra LF on end-of-message?

Hi!

When I run "echo test | exim test" and deliver mail for user test
to pipe, I see two empty lines after line "test". Why? The same
command with sendmail shows no empty lines at the message end, and
I think it's right. And one LF should be added when local delivery
to the mailbox. This empty lines added by exim are collected on
every message forward by pipe-robot or manual resend.
