 It still doesn't look quite right to me yet, though in slightly  
 different variations than the original PR is concerned with.
 
 The precedence of command-line setting now works, but the first two,  
 via_shell and via_assignment still show no output no matter whether  
 the variable is set on the command line or in the environment.
 
 However "make -e" still produces the broken output as before by the  
 looks of it.
 
 Something must be really confused inside the logic of how values get  
 set and when expressions are evaluated.
 
 $  make -f tvarset.mk all COMPILERS="from the command line"
 before:
 via_shell:
 via_assignment:
 via_for_loop: from the command line
 
 after:
 via_shell: from the command line
 via_assignment: from the command line
 via_for_loop:  from the command line
 
 direct use:
 from the command line
 $ COMPILERS="from the environment" make -f tvarset.mk all
 before:
 via_shell:
 via_assignment:
 via_for_loop: from the environment
 
 after:
 via_shell: from the Makefile
 via_assignment: from the Makefile
 via_for_loop:  from the Makefile
 
 direct use:

 $ COMPILERS="from the environment with -e" make -e -f tvarset.mk all
 before:

 after:
 via_shell: from the environment with -e
 via_assignment: from the Makefile
