yes I suspected that was the case:-)

In the simpler version that I suggested first, I changed the select not 
to pick up white space, but kept the simple adjacency test.

You do want to pick up the white space, but then you need a more 
complicated rule for testing adjacency.

Something like this, which doesn't quite handle white space as you asked 
(as it always pulls it into the grouped span) but may get you started.
