But that's not valid Fortran? Continued strings must use '&' at the
start of the continued lines as well? Eg gfortran 4.8.2 says:

    Warning: Missing '&' in continued character constant at (1)

Ie, you must write
  
   subroutine foo()
     print*, '&
          &end subroutine foo'
   end subroutine foo

in which case there isn't a problem.
