Author: dteske

New Revision: 309944
URL: https://svnweb.freebsd.org/changeset/base/309944

Log:
  Fix invalid parameter expansion (change $@ to "$@")
  
  Without quotes, $@ loses its special meanining (see below)
  
  % sh -c 'echo $@' /bin/sh "   1   " "   2   "
  1 2
  % sh -c 'echo "$@"' /bin/sh "   1   " "   2   "
     1       2
  
  The quotes are required to get ARGV to be unperterped
