[PATCH 0/1] MR2941: riched20: Set empty text by default in CreateTextServices.

[Santino Mazza (＠tati1454)]

This is to prevent NULL pointers when creating a standalone text service
that doesn't have any text set and then using functions like EM_SETSEL.
This NULL pointers doesn't happen when creating a richedit windows, because
it sets an empty text when the richedit window procedure handles the WM_CREATE event.
