I believe that ANSI C allows (at least the implementation I'm using does
without flagging it in the manual as a deviation)

fputs("Usage:   sltread [options] input-drive-name\n"
      "Options: [-l] [-s] [-v] [-x] [-z] [-t tape-volume-number]\n"
      "         [-d dataset-name] [-n dataset-number]\n"
      "         [-i ignore-count] [-r record-count]\n", stderr);

Thus you truly get ALL the advantages - a single function call, and even a few
null bytes saved.
