#  $(foreach ...) outputs its list separated by spaces, as normal. The problem
#  with this is that even if I embed $(NEWLINE) after each string, there is of
#  course still a space after the newline. If I then change the newline+space
#  for a newline, then that just leaves one undesired trailing newline at the
#  end that results in a double empty line, but we can change that as well.
#  To make things clearer, I don't put a newline in with the $(foreach ...),
#  instead I put in the *text* 'NEWLINE_PLACEHOLDER', and then substitute that
#  out as described.
