* NEWS: "groups user" no longer outputs "user :"; you need at least two users. "groups" now processes options like --help more compatibly. * src/groups.sh: Implement the option-processing change. Handle user and group names with special characters more robustly. Report write errors instead of exiting silently with status 1. [doc/ChangeLog] * coreutils.texi (groups invocation): "groups" no longer prefixes the output with "user :" unless more than one user is specified.
