I thought you were suggesting to fold fputs()+putchar('\n') into
puts(), which is a change that does not break.  I didn't even know
that you were suggesting to make more changes that would break the
output.  After all, you said only "can be less explicit" without
saying which use of "stdout" you meant to make "less explicit" ;-).
