Indeed, rob is correct. In POE, the actual function name is 
'forward-search-history' and not 'history-search-forward'. This looks 
like the author of POE::Wheel::ReadLine was being particulary dyslexic 
at the time. I'll have words with him and get a patch submitted :). 
Furthermore, it probably shouldnt' dump error lines to the output stream 
like that as it's particularly unfriendly.
