The only drawback is that the old semantics for the -i flag in case a non-numeric argument is following are no longer fully supported (only if -i is the very last arg at all), since getopt(3) doesn't support the discticnction between numeric and non-numeric arguments. Make lpr also understand dashes as input pseudo filenames. This finally makes lp(1) fully comply with Posix.2.
