      Hi Thomas,

      Thank you for your help and hints ! :)

      More general: A interactive string-srectangle would solve a dozen of
      "problems" for which each a different solution may already exist.

      If the indentation "problem" would be my only concern, I wouldn't
      ask for such a "big" solution...

      NO CRITISM! :)

      Keep microemacsing!
