[Dovecot] Problem redirecting email using pigeonhole 0.4.0 (with patch)

[Andriy Syrovenko]

Hello,

Starting from the version 0.4.0 Pigeonhole adds "X-Sieve" and
"X-Sieve-Redirected-From" headers ending them with CR+LF, and then
copies the original message (including original headers) ending the
lines with LF-only. This causes troubles at least if using Exim (I
have not checked with other MTAs)- original message gets dropped, and
only the new pigeonhole-generated headers are sent out. The attached
file fixed the problem for me.
