[PATCH v2] Ignore encrypted parts when indexing.

[Jameson Graef Rollins]

It appears to be an oversight that encrypted parts were indexed
previously.  The terms generated from encrypted parts are meaningless
and do nothing but add bloat to the database.  It is not worth
indexing the encrypted content, just as it's not worth indexing the
signatures in signed parts.

Fixes missing colon.  Thanks Austin, Xavier.
