Comment 1 for bug 1597017

The parser is generating 2 match rules in the dfa off of the one text rule, they are the equivalent of
  mount options=(rw,make-slave) -> **,
  mount options=rw,

this is due to how the parser is trying to share rule generation for generic rules that don't specify a flag, and rules that specify them. When flags aren't specified multiple rule sets may need to be generated but only one matching the flags should when the flags are specified.
