Subject: [PATCH] cleanup IME_GetCandidateList / UILess_GetCandidateList - move
IME_ShowCandidateList, ImmGetContext and ImmReleaseContext to this function -
set ime_candpgsize to MAX_CANDLIST if dwPageSize is zero - comment out
deselection of ime_candsel in case of korean language for the moment
(LANG_CHT does not work anyway)
