Afaik,

CORE::warn "anything\n";

never includes the line number: messages with a new line always disable 
that feature. Bio::Root::RootI::warn /always/ puts new lines into the 
message, so they /never/ have the line number.

So its my understanding there will be absolutely no difference in 
behaviour following this change (except that warning can be caught by 
Test::Warn). I just wanted to confirm my understanding.
