Synopsis: tunefs error is incorrect when enabling softupdates

State-Changed-From-To: open->closed
State-Changed-By: linimon
State-Changed-When: Wed Jan 30 10:50:47 UTC 2008
State-Changed-Why: 
Volker Werth reports in a followup that this error does not recur on
6.x and 7.x.  I think we can safely close it now due to its age.
