+    これは元々 INT/DEBUG が正しく動いているか分からないからそれの確認の為に表示
+    していた。然し、スタックトレースと見るには不完全である。外部コマンドの実行
+    時には結局表示されないし、また、関数内で実行している場合でも DEBUG を用いて
+    いる事から関数内で一番最後のコマンドを実行していた場合には DEBUG が呼び出さ
+    れずに関数を抜けるのでそのフレームは抜ける。RETURN も一緒に trap すれば原理
+    的にはそのフレームの情報を抜き出せるが、其処までする程の事でもない。ユーザー
+    的には別に見てもよく分からないし、既定で off で良い気がする。
