          This function breaks a continous string without newlines
          into a a string with newlines inserted at every `len':th
          character.

          If `indent' is defined and is given as an integer, `indent'
          number of spaces are inserted after every newline. If
          `indent' is a string that string is inserted before every
          newline.

          If the first argument is an integer, the function simply
          returns 0.

          break_string() is *not* context sensitive.  It does not take
          account of periods '.' and new-lines '\n'.  This means that
          the result is not necessarily what you would expect.  My
          experience is that you should use one space after a period
          and do not embed new-lines in the text, but append them to
          the result of break_string().  If this format does not meet
          your tastes you may find break_string() to be inadequate.  A
          future revision of break_string() may allow different line-
          breaking semantics.  (Cygnus)
