I'll be tucking into the source (prickly stuff, being a C programmer  
at heart) to see whether I can add a method to return the 'actual'  
number of matches (ie, include collapsed numbers).  Thank heavens you  
have lots of debugging available...

Before I try that though, as an insider, can you offer any insights as  
to whether this is even doable (within reasonable timeframes)  
considering the existing code-flow, etc.  If it is, please feel free  
to drop as many breadcrumbs (wrt sections of code to study) as you  
feel you need to ;)

Thanks
