    In Symbolics 3600 Zwei in Release 6.0 Beta IIc,
    microcode TMC5-FPA-MIC 315, FEP 17, with UTIL, on Lisp Machine Tweety Pie:

    Is there some way of enabling this automatically by modifying the
    attribute list at the top of a text file?

I take it that by "text file" you mean "source file".  Apparently,
"Fill" in Lisp (or any) mode is not a recognized attribute-line
attribute.

It is not clear to me that it would be a good idea to add it; a couple
of issues are raised:

- The user interface semantic picture is muddied by the existence of a
  "nofill" property that is only recognized by Text mode;

- there would probably be considerable sentiment against having fill
  mode in Lisp mode forced on any person who edits of a file, given how
  likely it is to trip somebody writing long lines of code;

- there are actually two modes concerned with filling, Fill and
  Fill-comments.

I don't have much of the historical background for the present state of
things.  Perhaps others can comment on this.
