    tmac/an-old.tmac: Move setup of IN and SN to end.
    
    * tmac/an-old.tmac (TH): Move setup of rendering parameter registers IN
      and SN from here to the end of the file.  (There's no need to re-test
      whether they're set with every man(7) page that is rendered.)  Update
      comments.

        documented as preventing "looping" (presumably infinite) if
        someone calls a two-font macro with an inconvenient parameter;
