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

[Jinoh Kang (＠iamahuman)]

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.
