check-ignore: add -n / --non-matching option
If `-n` or `--non-matching` are specified, non-matching pathnames will also be output, in which case all fields in each output record except for <pathname> will be empty. This can be useful when running check-ignore as a background process, so that files can be incrementally streamed to STDIN, and for each of these files, STDOUT will indicate whether that file matched a pattern or not. (Without this option, it would be impossible to tell whether the absence of output for a given file meant that it didn't match any pattern, or that the result simply hadn't been flushed to STDOUT yet.)
