What real world app needs this?
I've been writing a patch to convert some text displays of the peer-to-peer application DC++ to use Richedit instead of standard Edit controls, stream in RTF, and would prefer to use the cleaner EM_SETTEXTEX mechanism than the EM_STREAMIN one, which requires keeping more state on the caller-side. The EM_SETTEXTEX version works fine on Windows, but I primarily use WINE and am attempting to get that working before committing this patch.
Also, regardless, it's still a deviation from Windows behavior.
