   Produces an indented report on an individual's families and all
   descendant families.  Details on individuals include NOTE lines, once.
   Line wrapping is done with indention maintained.

   At the beginning of main() is provided the means to easily change
   page width, tab size, and left margin.

   This is based on indiv3.ll, also by Robert Simms.

   Version 2.1:  30 May 2001, fixed the concatenation of multiple notes
                 so that two spaces are inserted before every note after
                 the first.  Thanks to M.W. Poirier for pointing this out.

   TODO: Clean up trailing spaces in output.
