Steve,

line 5 in the mock code I posted emits a warning, while line 4 doesn't.
Both lines are more than 72 chars in length.

      subroutine foo
      IMPLICIT NONE
      Integer stupid_dummy_variable1 ! stupid_dummy_variable1
      Integer stupid_dummy_variable2 
! stupid_dummy_variable2
      Integer stupid_dummy_variable3 
 ! stupid_dummy_variable3

      write(*,*) stupid_dummy_variable1,
     &           stupid_dummy_variable2,
     &           stupid_dummy_variable3

      end

If that part of the standard applies to inline comments as well, then 
I'd expect that both lines should emit a warning .
