[Bug 14280] New: Richedit's EM_SETTEXTEX ignores ST_SELECTION

http://bugs.winehq.org/show_bug.cgi?id=14280

Summary: Richedit's EM_SETTEXTEX ignores ST_SELECTION
           Product: Wine
           Version: 1.1.0
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: richedit

        ReportedBy: [e-mail]

EM_SETTEXTEX which supposedly obeys ST_SELECTION (see
http://msdn.microsoft.com/en-us/library/bb787954(VS.85).aspx ) but the
EM_SETTEXTEX handler ignores it, calling "ME_StreamInRTFString(editor, 0, (char
*)lParam);" either way, which via ME_StreamInRTFString causes ME_StreamIn to
delete the entire buffer and not just just that one selection.

I have checked that Windows XP does obey the ST_SELECTION flag as documented by
MSDN.

I suspect one fix is on the 1.1.0 version of
http://source.winehq.org/source/dlls/riched20/editor.c#L2184 , which should
probably set the second parameter of ME_StreamInRTFString to a true value.
