Bbhostgrep not finding host

I'd a user of the dbcheck.pl script that cannot find the dbcheck tag in the bb-hosts file with bbhostgrep. After some investigation I think he have 2 line in the bb-hosts file for that host and the second one have the dbcheck test but bbhostgrep could not find it.

I've tested with a snapshot of some days ago that I'm using in my test environment and it seems that also with the 4.2 i cannot get the host.

the bb-hosts contains: 0.0.0.0 testhost # smtp ftp telnet 0.0.0.0 testhost # noconn dbcheck

if i do bbhostgrep dbcheck i get nothing, if I do bbhostgrep smtp i get the first line.

He's using 4.1.2p1 and I'm using 4.2-RC-20060712.2
