/* This tests correct spacing of macro expansion output, as well as
   the line it falls on.  This is quite subtle; it involves newlines
   within macro arguments becoming spaces, but not if it turns out to
   not be a macro invocation.  Also, multiple macro invocations spread
   across many lines.
