ActiveSupport::SafeBuffer do not work with all the features of #gsub. Mind your strings, or fix this bug in ruby!

# normal:
1.9.3-p125 :004 > "foo".gsub(/(?<my_string>.*)/) { $~[:my_string]*2 }
 => "foofoo"

# broken:
1.9.3-p125 :005 > "foo".html_safe.gsub(/(?<my_string>.*)/) { $~[:my_string]*2 }
 => ""

# round trip, back to working
1.9.3-p125 :006 > "foo".html_safe.to_str.gsub(/(?<my_string>.*)/) { $~[:my_string]*2 }
 => "foofoo"
</my_string></my_string></my_string>
