Doesn't handle multiple bullet points properly

[nertzy]

Here is the file I'm editing: https://raw.github.com/Casecommons/pg_search/master/CHANGELOG.rdoc

It has bullet points in sections like this:

= PgSearch

== 0.3.3

* Backport array_agg() aggregate function to PostgreSQL 8.3 and earlier.
  This fixes :associated_against searches.

* Backport unnest() function to PostgreSQL 8.3 and earlier.
  This fixes {:using => :dmetaphone} searches.

* Disable {:using => {:tsearch => {:prefix => true}}} in PostgreSQL 8.3 and earlier.

== 0.3.2

* Fix :prefix search in PostgreSQL 8.x

* Disable {:ignoring => :accents} in PostgreSQL 8.x

etc.

This is valid RDoc syntax, but only the first asterisk gets highlighted as blue. Everything else in the rest of the file stays unhighlighted.

Thanks!
