Hello all.  I don't quite know if this is the place to post these types of
submissions but I cannot seem to find anywhere else.
  
Anyway,  I have made an update to pop.rb (from the ruby-1.6.8 distribution)
to give POP3 STAT command functionality (POP3#stat).  The method returns an
array of [numMessages, size].  I have also added a BadResponseError class to
the bottom like it is in smtp.rb since I could not find where BadResponse
(in the POP3#list method) was located and it seemed like a problem as it is.

I have attached a diff (pop_diff.txt) to this email and would be more than
willing to send the whole new file on request.
   
Comments and criticisms are welcome!
