Message 80634 - Python tracker

Further investigation ( grep -r getallmatchingheaders Lib/* ) reveals 
that in addition to having no tests, and being implemented incorrectly 
in http.client, getallmatchingheaders() is called only once, in 
http.server; that code is also broken (I reported this yesterday in  
#5053).

Maybe Python 3 is where getallmatchingheaders can make a graceful 
goodbye (and a 2to3 conversion added?).
