DOCBOOK-APPS: Space before a horizontal rule in headers

Hi,

The following TeX in jadetex.dtx in insertRule seems to be the one that
actuall inserts the horisontal rule, and seems to insert a standard line
worth of space while inserting the rule.
	
   \leaders\hrule height \LineThickness\hfill

Is there anyway that I can convince it that I do not want the space at the
beginning of the rule?

Regards
