  You are right:  I first copied manmac.tex's \leftheadline and
  \rightheadline into my document and then used the ideas in them to
  make a new macro that was actually used by \makeheadline;  but
  after making my macro, I did not delete the copies of
  \leftheadline and \rightheadline.  Then while experimenting with
  changing the \kern value, I made the changes in the unused copies
  rather than in the used new macro.

  By the way, thanks for the your post of Aug 10, 1998 which showed
  the modifications to the output macro.
