richedit: WM_SETTEXT must immediately autodetect URLs, without waiting for a WM_CHAR.

Hi Alex!
I just noticed a valgrind warning in richedit that might have
something to do with your new test code in
http://source.winehq.org/git/wine.git/?a=commit;h=38d7ba6eff6757b83b54b0485b3452a41de25470
The warning is:

 Conditional jump or move depends on uninitialised value(s)
    at  test_EM_AUTOURLDETECT (editor.c:1559)
    by  func_editor (editor.c:4203)
    by  run_test (test.h:449)
    by  main (test.h:498)
  Uninitialised value was created by a client request

Could you have a look at it?

Thanks,
