 /*
-  Reliable messages and their meanings (note that any message may be missed if bug.n is hung):
-        1 - Window shown (shown ID)
-        2 - Window destroyed or hidden, same message for both (destroyed or hidden ID)
-        4 - Window activated via mouse, alt+tab, or hotkey (sometimes 32772, but always one of them)
-        6 - Window title change (ID of redrawn window)
-       13 - Hung window recovers and replaces ghost window (ghost window ID is provided)
-       14 - Hung window recovered (ID of previously hung window)
-    32772 - Window activated via mouse, alt+tab, or hotkey (sometimes 4, but always one of them)
-    32774 - Window is flashing due to some event, one message for each flash
-
-  Indications of:
-    New windows
-      cmd/shell may be starting a new window on message 6
-      Win+e indicates a new window with message 6 as long as the button
-      presses are below a certain frequency.
-      Message 1 may indicate a new window started from Windows Explorer.
+  Reliable messages: 1, 2, 4, 6, 13, 14, 32772, 32774. Any message may be missed, if bug.n is hung.
+  Indications of a ...
+    new window:
+      6:     Cmd/shell may be starting a new window.
+      6:     Win+E indicates a new window, as long as the button presses are below a certain frequency.
+      1:     Maybe a new window started from Windows Explorer.
       There doesn't seem to be a reliable way to get all application starts.
-    Closed windows
-      13 always indicates closed ghost window
-       2 always indicates closed standard window
-    Focus change
-       4 or 32772 always catch this
-    Window event
-      6 indicates when title changes which can be used
-      in the case of some applications, 32774 works for others
+    closed window:
+      13:    Always indicates closed ghost window.
+       2:    Always indicates closed standard window. (?)
+    focus change:
+      4:     Always catch this!
+      32772: Always catch this!
+    window event:
+      6:     Title changes, which can be used in the case of some applications, ...

       Windows events can't always be caught.
