To be honest I was not sure this was new in ANSI. We are not talking
about cpp "#" and "##" operations. What I think we are talking about
is writing:

                  printf("A very long string. Warning: unacceptable argument to %s instruction", insn);

as

                  printf("A very long string."
                         "Warning: unacceptable argument to %s instruction\n",
                          insn);

If this is not acceptable, what is the preferred way to do this? I'd
sooner not make it two printf's and I think

                  printf("A very long string.\
Warning: unacceptable argument to %s instruction\n", insn);

Is almost as ugly as just letting the line wrap.
