class definition parse error

[Joe Buehler]

According to the debug output this does not parse correctly:

samba_is_setup = ( ReturnsZero(/bin/sh -c 'test -f
/usr/local/lib/samba/var/runflag.$(host) || test -f
/usr/local/lib/samba/var/runflag.$(fqhost)') )

The problem appears to be that the ReturnsZero is declared to
end at the first ) character.  Using {} braces instead
for the variables fixes the problem.
