New Revision: 213883
URL: http://svn.freebsd.org/changeset/base/213883
Log:
Embellish this testcase a little bit to be more clear what the output is
and why. The first case is correct usage which has but one correct output.
The 2nd and 3rd cases are incorrect usage in which the exact output is
not standardized and various shells give various allowable output.
