RE: coreutils 5.2.1 bug: id -Gn

[Bulgrien, Kevin]

My broken mailer grunged the examples.  I'll append ; to each
command so output is more distinguishable, and try again.

This may not be a source package bug.  I observed this behavior
on a Mandrake 10.1 Official box (coreutils-5.2.1-4mdk.i586.rpm)
and tried also Mandrake Cooker (coreutils-5.2.1-5mdk.i586.rpm).

A Gentoo user I know reports that id -Gn ; (5.2.1) appears to
work as it should.  I wonder what might cause the broken
behavior to occur?
