New Revision: 198491
URL: http://svn.freebsd.org/changeset/base/198491

Log:
  Fix parsing of mount options specified with -o in case an option with
  value is preceded by an option without value (for example -o
  option1,option2=value). Options must be separated before searching for
  '='. Also compare pnextopt explicitly against NULL.
