[Dovecot] Dovecot / Sieve

[Joan]

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
