Subject: [PATCH] John's fix for the minimize/close/maximize controls no longer
 working. WIN32 expected us to pass the message on up the chain (or do
 something else with it), rather than just throwing away the event, for a
 certain class of events.  (See the diffs for more details.)

The code is also slightly reformatted from what was previously in the
repository.
