Yep - my level of parenthesis.  Your solution is the same as mine in
using two join processes, with the second using stdin produced by the
output of the first; I just nested them via bash <() process
substitution instead of pipes.

However, it does beg the question - is there any technical reason WHY
join must not accept more than two files?  It seems like that might be a
nice GNU extension.
