问题描述
某些事情必须解释这一点，但是对我来说，这目前没有任何意义：）
如果您具有以下三个变量：
(setf l '((( "NAME" "HASH-TABLE" )) ("&BODY") ("BODY")))
(setf fs "WITH-HASH-TABLE-IteraTOR")
(setf doc "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")
使用以下指令对其进行格式化：
(format NIL "~a ~a ~a" fs doc l)
我得到输出：
"WITH-HASH-TABLE-IteraTOR 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 (((NAME

请注意，换行符位于打印列表的末尾。我希望一条直线没有任何换行符。这一定是来自SBCL，并且不是长字符串的命令行行为，因为(format NIL ...)在字符串中给了我类似的输出。该行为在SBCL> 2.0中也是新的。
是否缺少某些控制变量，例如*print-level*？
