	* Fix tagging of IPAddrs in header lines.

IPAddrs in header lines weren't being tagged due to a defect in the
code.  Below is a simple test showing the difference between 0.16.4 and
0.17.3

## echo Received: test at example.com 1.2.3.4 | bogolexer-0164 -p
rcvd:test
rcvd:example.com
1.2.3.4

## echo Received: test at example.com 1.2.3.4 | bogolexer-0173 -p
rcvd:test
rcvd:example.com
rcvd:1.2.3.4

What's happening is that "rcvd:1.2.3.4" doesn't appear in your wordlist,
so can't be used for scoring a message.  With some training, bogofilter
will begin to recognize "rcvd:1.2.3.4".

Are you referring to transaction processing in the database?  Look for
getenv in datastore_db.c :-)
