(1-2) These require pkuthss to drop its GBK support, which is perhaps not going to happen soon.
(3) LaTeX defaults to \flushbottom, while MS Word defaults to somethings like \raggedbottom; the bottom setting was chosen to make their number of lines in an average page equal. KEY WORDS is only used in the ugly mode because "keyword" is almost invariably used instead of "key word" in the native English corpus as far as I know.
(4) I think this needs a transition phase, where a comment is placed next to the code fragment to be eventually removed.
