PS.  Yours works better: mine fails on the double slash '//' because it
insists on looking for a non-slash item right after it and so produces
'/a/.b///1' when it should have given me '/a/.b//c/1' as yours did.  It's
somewhat academic as in processing prompts the regex should never encounter
two slashes with nothing between them, but ... I prefer the more correct
answer.  Thanks.
