Don't block '-' in replacement patterns
Don't block '-' in replacement patterns

There are some libraries that uses blacklists which might contain '-' in
a string that refers to a class or package name (e.g. Jetty[1]). There
is no way to define a rule to cover such cases as jarjar prohibits '-'
in replacement patterns.
