title: Align symbols in plist
body: <p>How can I align symbols in a plist? Take the following examples of default <code>'emacs-lisp-mode</code> indentation</p>
  
  <pre><code>'(:a 1
       :b 2
       :c 3)
  
  (defhydra h (:color amaranth
                      :pre some-pre
                      :post some-post)
    nil)
  </code></pre>
  
  <p>How can I achieve the following indentation?</p>
  
  <pre><code>(defhydra h (:color amaranth
               :pre some-pre
               :post some-post)
    nil)
  </code></pre>
  
  <p>On a side note, is there a similar function for lisp like <code>c-show-syntactic-information</code> which is incredibly useful for this type of thing. I can't find anything with <code>apropos</code>.</p>
