uniq: add the --group option
* src/uniq.c (usage): Summarize the new option, and adjust the --all-repeated option to be more consistent. (check_file): Merge the --group functionality into the core loop for the default uniq operation since it's very similar and can output lines immediately upon reading. (main): Handle the new --group option and make it mutually exclusive with other selection options. * tests/misc/uniq.pl: Add tests. * NEWS: Mention the new feature. * doc/coreutils.texi (uniq invocation): Describe --group.
