cus-misc: customize autoloads, environment variables (and key bindings)

[Simon Josefsson <jas@extundo.com>]

There were some discussion on cus-misc.el before, and I think one
comment was that the key binding part should use a better widget for
entering keys than the custom "string" widget.  But what do people
think of the other parts?  Autoload cookies and environment variables?
Do anyone think it would be useful to add this to Emacs?  If so, we
could add the following except for the custom-key-alist part, until
someone look into making a better key binding widget.

I just realized adding entries to `load-path' could be made
customizable with this approach as well.  And `auto-mode-alist' is
another example.

;;; Commentary:

;; Put this file in your load-path, evaluate it, and run M-x
;; customize-variable RET custom-key-alist RET and add some key
;; bindings, for example:
;;
;; custom-key-alist's value is
;; (("<f5>" . compile)
;;  ("<f6>" . next-error)
;;  ("<f7>" . previous-error)
;;  ("C-x 4h" . gtk-doc-insert))
;;
;; Click on 'Save', and restart Emacs to enjoy the now (hopefully)
;; automagically configured new global key bindings.
;;
;; Similarly, customize `custom-autoload-alist' and
;; `custom-environment-variable-alist' to add autoload cookies and
;; environment variables, respectively.  For example:
;;
;; custom-autoload-alist's value is
;; ((mail-add-payment . "hashcash"))
;;
;; custom-environment-variable-alist's value is
;; (("CVS_RSH" . "ssh"))

;;; History:

;; 2003-12-30 initial release
;; 2003-12-30 second release, fixed comments and added :require to defcustom.
;; 2004-01-04 added autoloads and environment variables,
;;            renamed to cus-misc.el.
