Bug #446: [PATCH] [DOC] Net::HTTPHeaders#fetch does not return nil but raises IndexError
http://redmine.ruby-lang.org/issues/show/446

Author: Arthur Schreiber
Status: Open, Priority: Normal

As Hash#fetch, Net::HTTPHeaders#fetch does raise an IndexError when neither a default 
value nor a block was passed and the requested key can not be found.

The attached patch updates the documentation for Net::HTTPHeaders#fetch to reflect this.
