richedit: bCaretAtEnd should not be reset from rewrapping text.

The bCaretAtEnd value in ME_TextEditor is used to identify that the caret is at the end of a wrapped line instead of the start of the next line in the paragraph since both these positions correspond to the same position in the document. The bCaretAtEnd value was previously being set back to FALSE whenever the window was resized.

richedit: bCaretAtEnd should not be reset from rewrapping text.
