I haven't touched instances of "behaviour", "dequeue", "removeable",
"resizeable", or "removeable" because all are accepted variant spellings
and I don't know what the policy is on such things.
Books and web pages seem to prefer the requestWindowFeature method
over the android:theme, despite the advantages of the latter. This
may be because we mention requestWindowFeature but not android:theme
in our FAQ.
(Also add missing end tag to fix page rendering with Chrome.)
