Subject: [ruby-talk:19861] BUG(!) in unescapeHTML

require 'cgi'
txt=CGI::unescapeHTML(' ')

results for me:
/cygdrive/c/RUBY/lib/ruby/1.6/cgi.rb:302:in `unescapeHTML': undefined
method `[]' for nil (NameError)
	from /cygdrive/c/RUBY/lib/ruby/1.6/cgi.rb:274:in `gsub'
	from /cygdrive/c/RUBY/lib/ruby/1.6/cgi.rb:274:in `unescapeHTML'
	from test.rb:3

logical fix is to add
      when /\Anbsp\z/ni          then ' '

to the case statement on line 277, but this same error will crop up
for any other ampersand case the statement is unprepared for...  which
seems like a flawed way of doing things.  perhaps the logic around
line 302 could be re-worked.
