Hello,

This patch solves annoying problem with `define-inline' forms not being
indented correctly unless inline.el is explicitly loaded.

For illustration, try to open the following foo.el file:

(define-inline org-element-type-p (node types)
  "Return non-nil when NODE type is one of TYPES.
TYPES can be a type symbol or a list of symbols."
  (if (inline-const-p types)
      (if (listp (inline-const-val types))
          (inline-quote (memq (org-element-type ,node t) ,types))
        (inline-quote (eq (org-element-type ,node t) ,types)))
    (inline-letevals (node types)
      (inline-quote
       (if (listp ,types)
           (memq (org-element-type ,node t) ,types)
         (eq (org-element-type ,node t) ,types))))))

with emacs -Q, indenting the file will yield different results with and
without executing (require 'inline).

With the patch, indentation becomes consistent.

Subject: [PATCH] lisp/emacs-lisp/inline.el: Autoload public macros

* lisp/emacs-lisp/inline.el (inline-quote):
(inline-const-p):
(inline-const-val):
(inline-error):
(inline-letevals): Autoload macros that may appear inside
`define-inline'.  This is necessary to load the indentation rules when
Elisp code that uses `define-inline' is edited.
