+* Teach eww about <code> tags
+
+  Strangely enough, ~eww~ doesn't seem to be aware of =<code>= HTML tags.
+  Luckily it's trivial to teach it. It does know about =<pre>= HTML
+  tags, and basically I just want =<code>= tags to be treated almost as
+  =<pre>= tags, so to do that we just have to define a =shr-tag-code=
+  function. I've copied the =shr-tag-pre= function and removed the calls
+  to =ensure-newline=, because =<code>= tags are inline tags.
+
+  In order to remain a little future-proof, it should only be done if
+  it doesn't already exist.
+
+  *Note:* See my [[Vacuous defvar][note]] on vacuous defvar for this use of =defvar=.
+
+  *Note:* See my [[Function declarations][note]] on function declarations about the use of
+  =declare-function=.
