I found it.  Since my action was named jar, it tried to invoke the
main-target rule named jar, so it's not surprising it didn't do what I
wanted.

I wonder if it's worthwhile to try and issue a warning if a module's
top-level rule is overwritten.  Then I could just be sure to write an
explicit rule for every action and I'd be told when I was causing a
problem.
