[PATCH 1/1] winex11.drv: Call ImeSetCompositionString after IME_SetResultString

[Alex Kwak]

IME_SetResultString function overwrite composition strings. so, next
composition is not display on GUI. but, still have an xim. Therefore,
there was a string that seemed to have disappeared in the middle of the
input.

Therefore, change it as follows. When calling IME_SetResultString, if
in a Composition state, no longer generate WM_IME_ENDCOMPOSITION and
call back the previous Composition to recover the overwritten
Composition.
