In EWW, when a <input type="checkbox"> has no 'value' attribute, when it
is checked, its value is taken as nil (empty). According to HTML
specification, it should be taken as "on".
Example:
--------------------------------------------------
<form action="foo" method="get">
<input type="checkbox" name="box1" value="bar" checked="checked">
<input type="checkbox" name="box2" checked="checked">
<input type="submit">
</form>
--------------------------------------------------
If you open the above file and hit "submit", the request is:
foo?box2=&box1=bar
instead of:
foo?box2=on&box1=bar
Suggested patch:
--------------------------------------------------
diff --git a/lisp/net/eww.el b/lisp/net/eww.el
index 8918be0d2e..55eded6ce6 100644

Thanks; applied to Emacs 28.
I forget if I've asked you this before -- this patch was small enough to
apply without a copyright assignment, but in case there's more patches
in the future, an assignment might be necessary. So it might be a good
idea to start that process now -- would you be willing to assign the
copyright on Emacs patches to the FSF?
