// Fix for 4753116.
// If it is not win95 (we are using Richedit 2.0)
// we set plain text mode, in which the control is
// similar to a standard edit control:
// - The text in a plain text control can have only
// one format.
// - The user cannot paste rich text formats, such as RTF
// or embedded objects into a plain text control.
// - Rich text mode controls always have a default
// end-of-document marker or carriage return,
// to format paragraphs.
