inferior-lisp mode indenting problem

inferior-lisp mode indenting problem

[Lowell]

The auto-indenting of 'if' clauses in inferior-lisp mode is not working 
properly. It does:

(if test
     then
   else)

but it should do:

(if test
     then
     else)

How can I change it?

This is the way `if' should be indented in Lisp.

(put 'if 'lisp-indent-function 0) will get you:

(if test
    then
    else)

But beware that most other people reading your code will find this
style annoying.

To get proper indentation of Common Lisp code without clobbering
conventional Emacs Lisp indentation you could do something like so:

(add-hook 'lisp-mode-hook
   (lambda ()
     (set (make-local-variable lisp-indent-function)
          'common-lisp-indent-function)))

                                 Oh boy!  should be quoted, like so:

(add-hook 'lisp-mode-hook
          (lambda ()
            (set (make-local-variable 'lisp-indent-function)
                 'common-lisp-indent-function)))

I hadn't noticed before because the default value of
`lisp-indent-function' is `lisp-indent-function' !

This is the way that `if' _is_ indented in Emacs Lisp.  This is helpful
in separating the `then' (which is a single form) from the `else' (which
is several forms).

But what does _should_ mean here?  Who says?  What's the authority?

You're right.  I had forgottent that the `else' form doesn't have an
implied progn in CL (like in Emacs Lisp).
