That's not accurate.  See the variable
quail-translation-keymap.  A user can select the next/prev
group by typing C-n/C-p.  In addition, several input methods
(including chinese-py) remembers the last selection.  So, to
get a constant result, we must reset the indices of last
selected translation, which requires modifying contents of
(quail-map).

I think it's not worth working on quail-conv to make it work
correctly for all cases.  How about just make it work well
for simple input methods (i.e. ones that (quail-simple)
return t) and reject complicated input methods.
