You're right; the argument comes down simply to whether we would  
support \S+ or just \w+.  I'm neutral on this myself, but I wonder  
how allowing \S+ would affect other modules (for instance, indexing  
for a flat db), where one might just use \w+ for accessions,  
expecting them to be GenBank- or EMBL-like alphanumerics.  The fact  
that \S+ was supported in the past (as indicated in the bug report)  
and then wasn't post 1.2 makes me think there was a reason for  
someone going in and modifying it, but that was before my time on the  
group.

I'll have a look at the CVS history when I have time to see what I  
can dig up.
