Henrik Lissner e71daf5cc3 tweak(emacs-lisp): elisp indentation for data/plists
This was adapted from
https://www.reddit.com/r/emacs/comments/d7x7x8/finally_fixing_indentation_of_quoted_lists/.
It fixes the indentation of quoted data (and plist keywords) so they're
indented like data, rather than function arguments, like so:

  BEFORE:
    `(foo bar baz
          doom emacs)
    '(:foo 1
           :bar 2
           :baz 3)
    '(:foo 1
           2
           3
           :bar 4)
    (:foo 1
          :bar 2)
    (:foo 1
          ;; test comment
          :bar 2)
    (:foo 1
          2
          :bar 3)

  AFTER:
    `(foo bar baz
      doom emacs)
    '(:foo 1
      :bar 2
      :baz 3)
    '(:foo 1
      2
      3
      :bar 4)
    ;; only align unquoted keywords if keywords start each line:
    (:foo 1
     :bar 2)
    (:foo 1
     ;; test comment
     :bar 2)
    (:foo 1
          2
          :bar 3)

Also, I added a way to declare that plists in an macro's arguments
should be indented like data:

  (put 'map! 'indent-plists-as-data t)

  BEFORE:
    (map! :localleader
          :map emacs-lisp-mode-map
          (:prefix ("d" . "debug")
                   "f" #'+emacs-lisp/edebug-instrument-defun-on
                   "F" #'+emacs-lisp/edebug-instrument-defun-off))

  AFTER:
    (map! :localleader
          :map emacs-lisp-mode-map
          (:prefix ("d" . "debug")
           "f" #'+emacs-lisp/edebug-instrument-defun-on
           "F" #'+emacs-lisp/edebug-instrument-defun-off))

There was a third improvement I was hoping to include, namely,
proper indentation of interpolated forms:

  BEFORE:
    `(foo
      bar
      ,(if t
           'baz
         'boo))

    `(foo
      bar
      (if t
          baz
        boo))

  AFTER:
  `(foo
    bar
    ,(if t
          'baz
        'boo))

  `(foo
    bar
    (if t
     baz
     boo))

But this was removed because it breaks indentation for quoted macro
forms (or dynamic elisp programming):

  BEFORE: (good)
    `(with-temp-buffer
       (if (always)
           (message
            "Hello %s"
            user-login-name)
         (message
          "Goodbye %s"
          user-login-name)))

  AFTER: (bad)
    `(with-temp-buffer
      (if (always)
       (message
        "Hello %s"
        user-login-name)
       (message
        "Goodbye %s"
        user-login-name)))
