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.
