[PATCH 0/3] MR3208: riched20: Wrap marked paragraphs at Text Services initialization. (follow-up to !2941)
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.
