[Dovecot] Dovecot / Sieve

Hi,

As the "new Sieve implementation" is using a "gratefully stolen copy of deliver.c from dovecot" (i.e. a dirty code in mail-raw.c), would it be possible for the Sieve piece 1 - to be using files from dovecot directly rather than copying&changing it (which is very bad for maintenance) 2 - to be incorporated in the hg/mercurial tree of dovecot ?

Thanks a lot in advance,

Joan
