    Support HTML with formatting w/ "fallback" pic.
    
    Support pic(1) pictures when formatting HTML and using "fallback" pic
    macros.
    
    * tmac/pic.tmac (PS): Call `HTML-IMAGE` at end of macro definition.
    * tmac/pic.tmac (PF): Call `HTML-IMAGE-END` at end of macro definition.
      (`PE` and `PY` call `PF`, and so are also handled.)
    
    Fixes https://savannah.gnu.org/bugs/?65047> (2/2).  Thanks to Hans
    Bezemer and Dave Kemper for the report.
