Subject: 26.0.50; eww default duckduckgo search results always in error
Date: Tue, 07 Feb 2017 12:25:09 +0100

Entering keywords on eww always results in error. This
error aborts the rendering process although a render of the search
result page is displayed.

Example:
emacs -Q

M-x eww
emacs

Always a message with the following error is signaled:

error in process filter: eww-size-text-inputs: Wrong type argument: listp, ((:method . "post") (:action . "/html/") (hidden :name "kl" :value "us-en"))
error in process filter: Wrong type argument: listp, ((:method . "post") (:action . "/html/") (hidden :name "kl" :value "us-en"))

`eww-size-text-inputs' calls `plist-put' on a list which is not actually
a plist.  Since [1: 03a012a796] `plist-put' is a bit more strict, it
requires the list to have an even length, hence the error.

Before:
(plist-put (list 99) :x 2) ;=> (:x 2 99)

After:
(plist-put (list 99) :x 2) ;=> Lisp error: (wrong-type-argument listp (99))

  Make FOR_EACH_TAIL more like other FOR_EACH macros

This should be fixed on master now.
