The point of the indirection is to get macro arguments expanded *before*
substitution. Which matters only (I think) when using the # and ## cpp
operators. Example: gcc -E on this file

  #define S1(x) prefix_##x
  #define S(x) S1(x)
  #define FOO bar
  S(FOO)
  S1(FOO)

produces

  prefix_bar
  prefix_FOO

That would certainly cause some additional confusion. Any suggestion for
appropriate m4 quote characters to use? ;-)
