missing mandatory blanks in f18 demo

[schauveau]

I noticed that the fortran parser is treating most (all?) blanks as optional between adjacent keywords.
The following source code is accepted as valid even though each line with a 'hoops' comment should be illegal:

subroutinefoo(a) ! hoops 
  class(*) :: a
  selecttype (a)    ! hoops 
     typeis (integer)  ! hoops 
        print *, a 
     typeis (real)  ! hoops
        print *, a 
  end select
endsubroutinefoo ! hoops

Reminder: See also p53 table 6.2 "Adjacent keywords where separating blanks are optional" in F2015 standard draft
