When `is-auto-insert' is t, manued.el inserts defcommands in the
current buffer in the case of no defcommands in the buffer.  If
`is-auto-insert' is nil, manued.el does not insert defcommands.

When the second element `is-query-when-insert' is t, manued.el asks to
user `insert-manued header (y or n)', otherwise no question. This is
only effective when `is-auto-insert' is t.

The third element of this list `insert-point' indicates insert point
of defcommands. The meaning of value is as folowing.

`is-auto-insert' が t の場合，もし現在のバッファにdefcommandが無い場合に
はmanued.elはdefcommandを現在のバッファに挿入します．nilの場合には何もし
ません．

2番目の要素`is-query-when-insert'がtの場合，manued.elはユーザに
defcommandを挿入して良いか尋ねるようになります．nilの場合には尋ねません．
これは，`is-auto-insert'がtの場合に有効です．

Evauate last manued command from now point. Same as eval-last-sexp.
When argment is setted, reciprocal mode is used. Ex. when now mode is 
show-newer, then evaluating with show-older. However this command
search backword and using first matched l-parenthesis-str, this
command mistakes interpretation for the command. 

Ex. `[A/B; [a/hello]' must be `B' in manued fashion, may evaluated to
    `[A/B; hello'

直前の一つの真鵺道コマンドの評価を行う．eval-last-sexp と同様．引数を
与えると現在が newer ならば older を，というように逆の動作をする．ただ
し，後方から最初にマッチした manued-l-parenthesis-str を探すので，コメ
ント内部に真鵺道コマンドがある場合には正しく処理されないかもしれない．
