PGE will assume {*} at end of every regex

[pmichaud]

Per Synopsis 5, all regexes will have an implied {*} marker at the end of every regex, which results in calling an associated action method if one is supplied.

This may affect existing grammars that have an explicit {*} at the end of the regex (resulting in the action method being called twice). It can also affect grammars that assume that the action method will always have two arguments (e.g. if all other {*}'s in the regex have #= tags).
