The most significant thing is that the comments about MaxKeepAliveRequest and KeepAliveTimeout each precede the other's option in httpd.conf. I've also changed a few more option comments to begin with "NameOfComment:" for consistancy and to make it easier to look or grep through the file for the documentation on an option. I've also added a few options that were in older versions. They work for me. I've hand-edited the patches, which were against my own config files, so as to (I hope) avoid changing anything from the default, so there'll probably be some fuzz.
most of these cosmetic changes are incorporated into a forthcoming errata release of Apache.
