[1/2] richedit: Scroll up with less than page of text with ES_DISABLENOSCROLL.

[Dylan Smith]

When there is less than a page of text, the richedit control scrolls up
to the top of the text regardless of whether the ES_DISABLENOSCROLL
style is used or not.

This can be tested by:
1. Adding the ES_DISABLENOSCROLL style to wine's wordpad
2. Run wordpad
3. Enter more than a page of text
4. Select from the first page of text to the end of the text
5. Delete

The text should be scrolled to the top of the text as done by native
richedit controls, but instead was being scrolled just enough to show
the cursor.  This patch fixes this bug.
