[PATCH 2/2] user32: Call UpdateWindow() after showing a dialog.

[Sebastian Lackner]

From: Sebastian Lackner

This partially reverts 52146f62fd28bc1a791734b9939378267140b095.

As stated in that commit, a WM_PAINT will eventually be generated via window
exposure. However, some applications rely on WM_PAINT being sent synchronously.
As create_visible_dialog_seq shows, this happens reliably, and the behaviour is
specific to dialogs.

The indentation looks a bit awkward now.
