Rexml warnings

Hi,

Did anyone notice that with the 1.8.0 preview versions rexml starts
complaining during startup?

c:/program files/ruby/lib/ruby/site_ruby/1.8/rexml/entity.rb:21:
warning: character class has -' without escape c:/program files/ruby/lib/ruby/site_ruby/1.8/rexml/entity.rb:21: warning: character class has-’ without escape
c:/program files/ruby/lib/ruby/site_ruby/1.8/rexml/entity.rb:21:
warning: character class has -' without escape c:/program files/ruby/lib/ruby/site_ruby/1.8/rexml/entity.rb:21: warning: character class has-’ without escape
c:/program files/ruby/lib/ruby/site_ruby/1.8/rexml/doctype.rb:196:
warning: regexp has `]’ without escape

Should this be mentioned here, or at a rexml specific list?

Ronald.
