Ok, why do you want it still?  Removing it fixes a few problems with  
the help files:

- allows the placement and the name of the help patch to be flexible  
(i.e. object.pd, object-help.pd, and help-object.pd all work, and from  
anywhere in the helppath).

- allows helpfiles to work properly with geiger namespaces:  
[mylibrary/myobject] will look for its helpfile with the name  
[mylibrary/myobject],  [myobject] will look for the help patch in the  
path.  This means that you have have as many [prepend]s in your patch  
as you want and all of them will get the correct help file.

Ok, didn't know, that's good news.  But I guess I can't make the edits,  
right?

 From the sed man page: "any character other than a backslash (``\'') or  
newline character may be used to delimit the regular expression by  
prefixing the first use of that delimiter with a backslash"  ie.  
\xabcxdefx turns abc into def.  I think you can also use "s" instead of  
the backslash AFAIK.  I looooove regexps!
