    	Ah, I see.  I take it this means it is not possible to use sapply 
with strapply directly.  (I'd have to write a function that wraps 
strapply with different argument names, and then sapply that.)  Anyway, 
I managed to do what I wanted by collapsing my multiple regexes into 
one, so it's good for now.  Thanks for the help.
