riched20: Wrap marked paragraphs at Text Services initialization.
Today, CreateTextServices() returns an Rich Edit object without row
    start and end marks, which are expected to exist by many Rich Edit
    operations as well as EM_* message handlers.
This leads to a crash when certain messages (e.g., EM_SCROLLCARET) are
    sent to the Rich Edit object via ITextServices::TxSendMessage(), unless
    ME_WrapMarkedParagraphs() has been called beforehand.
Fix this by calling wrap_marked_paras_dc() early in the initialization
    process.
This is not a problem for windowed Rich Edit controls, which already
    calls ME_WrapMarkedParagraphs() before the user or application starts
    interacting with it.
