    tmac/an-ext.tmac: Set PD to 1v in examples.
    
    Use a vertical spacing of 1v between paragraphs in man page examples.
    This looks better (on typesetter devices like PostScript and PDF) with
    the Courier font family also used in examples.  Typewriter devices (like
    the terminal) already used an inter-paragraph spacing of 1v.
    
    * tmac/an-ext.tmac (EX): Save the value of the PD number register
    (inter-paragraph distance), and set it to 1v.
    (EE): Restore previous value of the PD register.
