Re: Indentation of LISP code

[Richard Stallman]

    Do you prefer that the line 

    ( defun  ( x &optional a b  c d)

    after applying an indent-function

    stay in the same form,

Yes.

                           or to be rendered so:

    (defun (x &optional a b c d)

Definitely not.  Indentation commands should not alter whitespace
within the code.  They should change the indentation of code and
comments, but not internal whitespace.
